Prague: Old Town Medieval Underground & Dungeon Tour

Summary

Prague’s hidden medieval world below the cobblestones with secret labs dungeons and stories you can’t see from the street

You’ll step down into Prague’s medieval underground with a local guide, exploring hidden tunnels, an old alchemist’s lab, and a real dungeon beneath Old Town. Hear stories you won’t find in guidebooks and notice details most people miss above ground. The feeling of emerging back into daylight stays with you long after.

What’s the experience like?

The first thing I noticed was the way the air changed as we left the sunlight behind in Prague’s Old Town. Our guide, Jakub, had this dry humor—he joked that we were about to meet “the real Prague,” which I guess sounds dramatic but honestly felt true once we started down those stone steps. The walls were rough and cold under my hand, and there was this faint smell—damp stone mixed with something old, maybe dust or history itself. I kept thinking about all the people who’d walked here before us, centuries ago.

I didn’t expect to laugh so much on a dungeon tour, but Jakub made sure of it. He pointed out weird little carvings in the underground rooms and told stories about alchemists who tried (and failed) to make gold right where we stood. There was one spot he called the “secret laboratory”—the shelves still held old glass bottles caked with grime. Someone in our group asked if any ghosts had ever shown up; Jakub just grinned and said, “Only when tourists leave their phones on.”

The dungeon part felt different—quieter somehow. The air got colder, or maybe it was just me getting nervous. You could see scratches on the walls if you looked close enough. It’s strange how your mind fills in the blanks down there. At one point, I caught myself whispering without even meaning to. When we finally climbed back up into the light, everything outside felt louder and brighter than before. I still think about that silence sometimes—you know?
