Cambridge Audio Tour: From the Bridge of Sighs to the Mysteries of the Market

Right ahead is a big grassy hill rising out of a neatly kept lawn, like someone plunked a mini-mountain in the middle of Cambridge. It’s hard to miss-just beyond that hedge. Welcome to Castle Hill, one of Cambridge’s oldest hangouts. About 2,000 years ago there were no colleges, no bikes, no cafés-just trees and open ground, and a few Romans scouting for a smart spot to settle. They picked this hill and called their village Duroliponte. Sounds like a spell from a wizarding exam, doesn’t it? The location was perfect: right by the river, great for crossing the water and for spotting trouble before it arrived. Later, in the Anglo-Saxon period, the hill became a fortress-a safe place locals could retreat to when things turned nasty. Then the Normans showed up, building castles the way we build sandwiches. In 1068, a huge castle went up here. The castle’s gone now, but the hill remains: “the mound.” And if you spot a red tile in St Peter’s Church up ahead, that’s a Roman leftover-ancient Cambridge, already collecting souvenirs.

Right in front of you is a handsome pale-stone building: three arches on the ground floor, neat rows of windows above. Look straight ahead to the middle of the courtyard and you’ll spot the words “Bibliotheca Pepysiana” sitting proudly over the central arches. Now picture yourself as a nosy 17th-century student, arriving here with big curiosity and slightly muddy shoes. Could there really be more than 3,000 hidden treasures inside? Oh yes. This all starts with Samuel Pepys, a man who loved books the way some people love butter biscuits… possibly more. He collected everything: printed books, handwritten manuscripts, maps, engravings, and of course his own diaries, stuffed with the everyday drama of his life. When Pepys died in 1703, he left the entire collection to Magdalene College. And he wasn’t casual about it. He insisted nothing should ever be removed or added, and everything must stay exactly in its arranged order. So if you get the urge to “just straighten that shelf,” imagine a stern librarian sighing from beyond the grave. Up on the first floor of this Pepys Building, with its neoclassical Ketton stone façade, the Pepys Library still feels much like it did three centuries ago. Over the entrance you can read “Bibliotheca Pepysiana 1724,” the year the books moved in, under Pepys’s coat of arms watching like a wise old owl. Inside are the six original diary manuscripts, rare early printed books from the age of Caxton, old English choir books, Sir Francis Drake’s navigation almanacs, and even Isaac Newton’s own copy of Principia Mathematica. There’s also a collection of over 1,800 popular ballads, because Pepys had interests so broad he’d have been impossible to ignore on social media. The building began in 1670 and took years, with funding hiccups and advice from Robert Hooke; Pepys helped with donations, joking that a book without a home is like a boat without a river. The library often opens in the afternoon, so you can come back and play apprentice Sherlock among the manuscripts. Want more background on Pepys, the collection, or the building? Ask in the chat below.

Right in front of you is Cambridge’s own Bridge of Sighs: a covered stone bridge with pointed Gothic arches and those delicate lattice windows (that’s the crisscross stonework that looks a bit like a net). It links university buildings over the River Cam-look toward the stretch where the water slides quietly between two grand old college blocks. Now, here’s the tale. Back in 1831, with builders thumping away and stonemasons shaping blocks by hand, this bridge was finished at St John’s College. Henry Hutchinson designed it to connect the Old Court and the New Court, saving scholars a long detour. Almost immediately, people started calling it the “Bridge of Sighs,” after the famous one in Venice. Truth be told, they mainly share a roof and a reputation for romance-Cambridge doesn’t really do exact copies. Local legend says Queen Victoria often passed by and named this her favorite little corner of Cambridge. Picture her carriage rolling along, the Gothic windows catching the light, and the faint idea of royal footsteps echoing in your imagination. Did she sigh for love? For beauty? Or because someone made her sit through another earnest university speech? We’ll never know. But Cambridge being Cambridge, it’s also a stage for legendary student mischief. One night in the 1960s, students used boats to haul a small Austin 7 under the bridge and hang it up with ropes. No damage-just a story that still gets laughs. A few years later they tried again with a Reliant Regal. Same result: bridge unbothered, students delighted. It’s had its film-star moments too: scenes from Elizabeth: The Golden Age and The Theory of Everything were shot here, and even Pink Floyd used it for a music video. So as you look up, imagine the sighs, the jokes, the cameras-and the occasional misplaced car. In Cambridge, boredom rarely gets a degree.

Right in front of you is a broad sweep of rolling green running along the banks of the River Cam. Big old trees, neatly kept lawns, and-over on the left-cows taking their job as professional grazers very seriously. To get your bearings, just look across the water: historic bridges and those polished college façades line up like a postcard that Cambridge somehow manages to look like every single day. Welcome to the Backs-Cambridge-speak for “the back” of the colleges. Which is hilarious, because this “back” is absolutely the show-off side. Picture it a few centuries ago: no cars, no city roar, just the quiet glide of the Cam… and maybe a cow offering a thoughtful moo in protest at yet another Latin lesson. This green corridor is the university’s outdoor catwalk. Seven colleges open their gardens and courts right here, letting their historic buildings drift down to the water’s edge. You’ll spot St John’s with its graceful bridges, Trinity with its turrets, plus Clare, King’s, and Queens’-each with its own look, and those tempting bridges that practically dare you to cross and wander straight into another era. Back in the 16th century, though, it was much more practical: plain pasture for sheep and cattle, a few orchards, and not much like today’s immaculate lawns-except for the color green… and the occasional animal cameo. In fact, the lawn behind King’s College still has placid cows on it, to the delight of tourists, students, and, yes, probably someone studying cows. In Cambridge, anything can become a subject. Over time, the colleges decided the river crowd deserved a good view, so they planted tree-lined avenues, built prettier and prettier stone bridges, and landscaped these grounds like open-air drawing rooms. But there was drama: in the 1700s, the famous landscape designer “Capability” Brown wanted to remake the whole area into a grand English park-removing some historic bridges to spotlight King’s College. Thankfully someone said, “Absolutely not,” or you might be staring at a huge lake instead of the Cam. By 2013, the Backs were named among the ten most beautiful views in all England, according to the president of the National Trust. And there’s a little mystery too: in the 1970s, many elm trees died from a serious disease, and the college gardeners banded together-like leafy knights-forming the Backs Committee to cut infected trees, replant, and debate what species should thrive for centuries. The committee later dissolved, but the Backs endured. Today there’s a plan to make it even greener, with more trees, hedges, and wildlife corridors-so even a fox or an owl can feel like it belongs at the university. Take a good look around. If you hear a whisper in the branches, don’t panic. It’s probably just a retired professor trying out life as a squirrel. If you want details on the name, past and future development, or the gallery, the in-app chat is the perfect place to ask.

Right in front of you, the market bursts into color: stalls piled with fruit, vegetables, and fresh flowers, all tucked under big white canopies. Behind them rises the unmistakable silhouette of Great St Mary’s Church, keeping watch like it’s been appointed official supervisor of Cambridge shopping. Spot the large green umbrella and follow your nose toward the freshest produce. Welcome to Market Hill, the liveliest and most historic square in Cambridge. Picture this place centuries ago: merchants rolling in early, boots crunching on gravel, and a constant buzz of bargaining as people hunted for the best deal. This square has been the city’s beating heart since Saxon times. The narrow lanes around you act like little streams, funneling in curious visitors, stallholders, and hungry students, all drifting toward the market the way bees home in on honey. But Market Hill hasn’t only been about apples and asparagus. In the Middle Ages, it hosted a day Cambridge never forgot. On 16 June 1381, during the Peasants’ Revolt, townspeople, led even by the mayor, turned on the University, fed up with its privileges. Imagine the square packed with an angry crowd, and Margery Starre, a remarkably bold woman, dancing right in the middle while shouting, “Away with the learning of clerks, away!” And you thought Cambridge rebellion meant skipping your reading list. Within hours, the University’s records were destroyed here in a whirlwind of dust, chanting, and very determined dancing. There was also a famous fountain. In 1855, after a major fire cleared away old houses, a beautiful Gothic fountain was built, fed by clean water from Hobson’s Conduit, a man-made water channel. Sadly, it was almost completely demolished in 1953. Close your eyes: can you almost hear the splash of water, and the thud of apples hitting wooden counters? This square is a time machine with shopping bags.

Right ahead is Market Street-easy to spot by the bright shop windows and the busy pedestrian walkway. On your right, that classic blue WHSmith sign is basically your landmark, like Cambridge’s “you are here” sticker. Picture yourself dropped into the city’s lively center: coffee scents drifting from cafés, bicycles parked like they own the place, and the chatter of traders getting things done. Market Street links Market Square-where people once shouted out prices for apples and second-hand books-to Sidney Street. It’s long been Cambridge’s own little “highway,” only far more charming and blissfully car-free. On the east side, take a look at Holy Trinity Church. It was built over 600 years ago, and it still has that Gothic look-meaning pointed arches and dramatic stonework, like architecture with a flair for storytelling. Nearby is Henry Martyn Hall, designed by an architect who was friends with Norman Shaw, a big-name trendsetter of his day. It’s shops now, but it once drew people fascinated by far-off missions. Glance up toward Radcliffe Court for a modern twist, then listen for the buzz from Petty Cury’s ever-busy shopfronts. Keep your eyes open-this street loves a good story.

Ahead of you is a broad courtyard with a remarkably round lawn at its heart, framed by those classic Cambridge honey-colored buildings. Look for the white-trimmed windows, the flowers perched on sills, and the little clock turret keeping watch like a polite but judgmental chaperone. If you’re facing the green and spot the ivy-clad frontage on your right, congratulations: you’ve found Christ’s College. This place has serious pedigree. It all began in 1437, when William Byngham founded a college with a wonderfully blunt name: God’s House. His plan was forward-thinking for the time: train teachers for grammar schools, which were scarce enough in England that you’d brag about finding one. But Cambridge history loves a plot twist. After only a few years, the original site was sold off to King’s College, and the young institution had to relocate and reinvent itself. The big makeover came in 1505, thanks to the formidable Lady Margaret Beaufort, mother of Henry VII, whose generosity turned God’s House into Christ’s College. The name, apparently, was suggested by a bishop who also happened to be Lady Margaret’s personal confessor. Nothing like a spiritual advisor with branding instincts. As you stroll around this round court, picture the generations who’ve paced these stones before you. Two headline alumni: John Milton, author of Paradise Lost, and Charles Darwin, the father of evolutionary theory. Toss in a healthy number of Nobel Prize winners, and you may feel tempted to inhale deeply-purely for the academic benefits, of course. The oldest ranges, built between the 1400s and 1500s, wrap around the court: the Great Gate, the Master’s Lodge (that’s the head of the college’s official residence), and the Chapel. The lawn is almost perfectly circular-almost-because students still occasionally attempt the timeless scientific experiment of punting a football from one end to the other. Also, take a look at the main entrance: the gate looks oddly “cut off” at the bottom because the street level has risen over the centuries, leaving the doorway with steps that now go down rather than up. On the right is the grand dining hall, restored in the 19th century by architect George Gilbert Scott. People still argue in there about philosophy, mathematics, and-inevitably-what’s for dinner. And here’s a quirky local rule: unlike in some colleges, students don’t stand up every time a fellow (that is, a senior academic member of the college) enters or leaves. Supposedly it’s a hard-won tradition dating back to a long-running dispute around the time of the English Civil War. Even Cambridge has its rebellions. Don’t miss the wisteria curling around the Master’s Lodge. In Second Court you’ll find the Fellows’ Building, put up in the 1640s. Through an arch lies the Fellows’ Garden, home to two mulberry trees-one planted in 1608, the year Milton was born. They’ve survived fierce storms, and though they now lean more than they stand, they still produce fruit every year. Tougher than a PhD thesis. And Christ’s best secret? A swimming pool. Yes, really: one of the very few historic university pools in England, fed by Hobson’s Conduit, and probably the oldest outdoor pool in the UK, dating to the 17th century. Christ’s is big on tradition: the Marguerites Club for top athletes, the oldest Boat Club in Cambridge, choirs, drama, and Shakespearean flair during the themed May Balls. Every two years the courts transform into a dreamscape-1920s Paris, Brazilian carnivals, even the Emerald City or A Midsummer Night’s Dream. So take a look around. You’re standing on centuries of stories, mysteries, and just a dash of brilliant madness. My advice? Don’t try to out-Darwin Darwin. Just enjoy the roundest-and maybe the cleverest-courtyard in Cambridge. If you want more details on the buildings, academics, or student life, open the chat section below and ask away.

Right in front of you, on the corner where Bene’t Street meets Trumpington Street, look for a big golden wheel that seems to ripple like melted metal. And perched on top, a rather judgmental-looking creature with a nasty stare. Congratulations-you’ve found the Corpus Clock. Now pause here, because Cambridge doesn’t usually do “street entertainment” like this. No marble lions, no noble kings on horseback. Instead, you get a mechanical monster that looks like it escaped from a slightly deranged scientist’s daydream-maybe even a Stephen Hawking nightmare. And that’s fitting, because the clock was unveiled in 2008 by Hawking himself. Not bad for a timepiece that looks like it’s always hungry. The face-more like a giant disc-is stainless steel plated in 24-carat gold, about a meter and a half across. There are no hands and no numbers. Time shows up through little openings lit by blue LEDs, arranged in rings across the surface. But let’s be honest: the star of the show is above it. That black beast-half insect, half dragon-has unsettling eyes and sharp teeth. It’s called the Chronophage, which literally means “time-eater.” Every time it snaps its mouth, it “eats” one second. Listen closely and you may catch a metallic clack, almost like a growl, as if it’s chewing the clockwork of your life. That chomping isn’t random; it’s part of the mechanism. The clock uses something called a grasshopper escapement. In plain English, an escapement is the part of a clock that releases energy in tiny, controlled steps so time can tick along. This particular design dates back to the 18th century and was invented by John Harrison. The Corpus Clock itself was created by John Taylor, who basically said, “Nobody understands how a grasshopper escapement works… so I’m putting it on display.” The result is the largest grasshopper escapement in the world-usually hidden inside antique clocks, but here it’s proudly out in the open, daring you to figure it out. The Chronophage also blinks-quickly-using golden eyelids. Miss the moment and you’ll swear it never happened. The whole system is powered by an internal spring, ready to snap into motion, and below it all hangs a large, pristine pendulum that gives the performance a strangely grand, ceremonial feel. Here’s the twist: it’s only truly accurate once every five minutes. The rest of the time, it acts moody-stopping suddenly, then racing ahead like it’s late for an exam. Taylor did that on purpose, as a reminder that life doesn’t move at a steady pace. There’s even a Latin inscription: “Mundus transit et concupiscentia eius”-“The world passes, and its desires pass with it.” A cheerful little thought for your photo break. This spot used to hold a Victorian bank, so the clock feels like a portal from sober old Cambridge into something delightfully sci-fi. More than 200 people helped create it-engineers, sculptors, jewellers, and even an official clock-keeper, just in case the monster gets a bit too peckish. And yes, the Chronophage has “siblings”: similar clocks exist on the Isle of Man, including one with a dragon, and another on display in Douglas. But this is the original-melting gold, unpredictable accuracy, and all. Stick around a moment. If you catch that rare double-blink, you’ll understand why no photo ever quite does it justice. It may eat seconds-but you get to keep the memory.

Right in front of you is an elegant shop window trimmed in dark blue, with “Fitzbillies” written in gold and the number 51. There’s usually a little black chalkboard sign by the entrance, practically winking at the street. Now, Fitzbillies isn’t just any bakery. This is Cambridge’s headquarters for the famously indulgent Chelsea bun: a soft, spiral sweet roll packed with sugar and cinnamon, sticky with syrup, and determined to ruin your willpower. It all kicks off in 1920, when the smell from this doorway lured in hungry students and curious professors alike. And this place has had more plot twists than a soap opera: bankrupt twice, in 1980 and 2011, plus a fire that shut it down for two whole years in 1998. In 2011, when it looked finished, Stephen Fry rallied support and persuaded food writer Tim Hayward to save it. Result: Fitzbillies rose again and now has three locations. Honestly, it’s hard not to “accidentally” buy two buns. Shall we go in?

Look toward the river and you’ll spot a graceful wooden arch bridge made from crisscrossed straight planks, linking two historic buildings of Queens’ College on the Cam. Welcome to our thirteenth and final stop: the famous Mathematical Bridge. And yes, I can hear your brain gearing up: “Mathematical? Where’s the giant calculator?” The trick is the engineering. Even though it curves like a wooden smile, it’s built entirely from straight timbers. It’s the sort of thing that makes you suspect a magician is hiding under the deck, or a math professor is pulling a prank. Picture Cambridge in 1749: rattling carriages, serious scholars, and the challenge of connecting the two sides of Queens’. The design came from William Etheridge, and it was built by James Essex, a craftsman celebrated for his skill with wood. Listen for a moment: water sliding beneath the bridge, and the chatter of people punting along the Cam. For centuries, students and visitors have crossed here wondering how straight pieces can form such a perfect arc. The secret is in the joinery, meaning the way the pieces lock together. The planks follow tangent and radial lines: in plain English, they’re set along directions that “hug” the curve and point toward its center, spreading the load so no single beam has to bend too much. Now, the legends. One tale claims Isaac Newton invented it using no bolts, and that curious students later took it apart and couldn’t rebuild it without adding bolts. Fun story… except Newton had already died before the bridge was built. And those bolts? They were there all along, cleverly hidden. It’s so iconic Oxford even made a copy in 1923. Not bad for a bridge that turns mathematics into a little bit of poetry over the Cam. Thanks for walking with me, explorer. If you ever need a bridge joke, you know who to call.
