Look for the dark stone, open-arched monument with a chunky carved base and a tall column on top, sitting right in the square at the end of Union Street.
Welcome to Castlegate... a small patch of ground with an outsized sense of drama. You can feel it in the way the space opens up, like the city takes a breath here. Officially it’s a central square; in local terms, it’s where Union Street runs out of road and Aberdeen’s history starts throwing elbows.
Up at the top end of the area, The Salvation Army Citadel stands with its castle-like look, and that’s no accident. This is the old stomping ground of medieval Aberdeen Castle, and Castlegate literally got its name from the castle gates that once stood here... until they were destroyed in 1308. Nothing says “new chapter” like knocking down the front door.
Castlegate was also the city’s practical “in and out” point: first trams, then buses, all funneling people through the same historic pinch point where merchants, soldiers, and ordinary folks have been passing for centuries.
And there’s a darker edge too. Just off the square is the Gallowgate, named for the gallows that once stood nearby. A little strip of old granite paving still survives in the bus lane by the courts... right around the spot where public hangings happened. The stones remember.
When you’re set, St Andrew’s Cathedral is a 3-minute walk heading northeast.
