Prague: Old Town Hall Underground Tour & Hidden Streets

Summary

Prague’s secret tunnels, ancient halls and lost street echoes

You’ll step beneath Prague Old Town Hall into medieval tunnels with an expert local guide, walk along an original Romanesque street buried below today’s city, and explore Angel College’s mysterious underground rooms—all included. Expect cool stone walls, surprising stories, and a new sense of how Prague grew from the ground up.

What’s the experience like?

“Don’t worry, it’s not haunted—at least not today,” our guide Jan grinned as he unlocked the heavy door under the Old Town Hall. I could smell old stone and something damp, like a cellar after rain. The air was cooler than outside, which felt good after the crowds up on Prague Old Town Square. There’s this hush underground—your footsteps sound louder, and even Jan lowered his voice a bit when he pointed out the crumbling archways that used to be someone’s living room centuries ago. I tried to imagine what it’d be like to have your front door open right onto a street that’s now buried under layers of city.

We ducked through narrow passages where the walls were rough and cold if you brushed them (I did, accidentally). Jan told us about how Prague kept building upwards over time—he showed us an actual medieval street, still there beneath everything. It was strange to see a road where no sunlight ever reaches. At one point, I caught the faintest whiff of old wood or maybe candle wax? Not sure if I imagined it. Someone in our group asked about ghosts again—Jan just shrugged and said you get used to odd noises down here. He seemed like he’d heard every question before but still answered each one with a little story or joke.

Afterwards we walked back up into daylight near the Astronomical Clock—the contrast almost made me squint. The square was busy as ever but I kept thinking about those quiet halls below, hidden right under everyone’s feet. We finished at Angel College’s underground rooms (included in the price), which felt less like a museum and more like stumbling into someone else’s secret basement. Honestly, I didn’t expect to feel so connected to Prague’s old layers—I still think about that cool air and those silent stones sometimes.
