Look up at that towering structure with its pale stone walls, the steeply pitched roof, and that distinct tower topped with a bright red spire.
We are standing outside St. Leonhard's Church, and let me tell you, this place is a masterclass in survival and reinvention.
Beneath the main floor lies a crypt, which is a subterranean stone chamber typically used for burials. Dating back to the year ten eighty, it is one of the oldest surviving historical interiors in all of Switzerland. But for a long time, before they could heat it in eighteen fifty nine, locals just used this sacred, ancient vault as a massive wine cellar. Practical, right?
But the ground around here held darker secrets. In eighteen ninety seven, workers tore down the old cloister to build a new prison wing. A local schoolgirl happened to be walking by and witnessed something terrifying. She saw open graves exposing the skeletons of medieval canons... the senior clerics of the church... all buried facing the building, still wearing the rotting robes they had been buried in centuries before.
The church had to be heavily rebuilt after a catastrophic earthquake leveled much of Basel in thirteen fifty six. Up in the roof of that massive tower, there is actually a giant wooden treadwheel. It is a medieval human powered crane used to hoist thousand pound stones, and it is perfectly intact today. They definitely needed it, especially when they hired Hans Niesenberger in fourteen eighty seven to expand the church. Hans was a controversial architect famous for taking on impossible structures, but he kept getting fired from other cities for massive construction flaws. Somehow, his work here stayed standing.
Then came the Reformation in fifteen twenty nine. Protestant mobs stormed the churches, smashing religious art in a massive wave of destruction known as an iconoclasm. But St. Leonhard's got lucky. A few brilliant, forward thinking citizens knew the mob was coming, so they secretly packed up the most priceless pieces... like the legendary Heilspiegel altar painted by Konrad Witz... and hid them safely away.
Remember that prison wing I mentioned earlier? By eighteen thirty five, the city converted the old monastery buildings attached to the church into a literal jail. Church leaders were absolutely furious. They thought putting criminals right next to a house of worship was a complete scandal. And it was definitely chaotic. In nineteen eighty five, several inmates pulled off a spectacular Sunday breakout, scattering across the region, with one fugitive sparking a massive manhunt after hiding in a nearby village.
The prison finally closed in nineteen ninety nine and was turned into a hotel and brasserie. The new owners proved they had a fantastic sense of dark humor, naming the place Au Violon, which is French slang for being thrown in the clink.
If you want to peek inside the church, it is open Tuesday through Friday from nine in the morning until five in the evening.
Take a moment to soak this incredible history in. When you are ready, we can head over to our next stop, the Music Academy Basel, just a short walk away.
