Understanding the Context

1. The Jewish Quarter’s Underground Secrets: Beneath the Cobblestones

While much of Prague’s Jewish Quarter (Josefov) draws crowds with its historic synagogues and museums, few realize the incredible network of hidden passageways and secret tunnels beneath the streets. Explore the Old Jewish Cemetery, one of Europe’s oldest Jewish burial grounds, then descend into mysterious underground corridors that once served as smuggling routes and hiding places during wartime. These unmarked tunnels offer chilling stories of resilience and danger, making them a profoundly moving yet compelling secret for visitors eager to uncover Prague’s layered history.

2. The Cellars of Sanitation: A Forgotten Underground Network

Key Insights

Dive into a lesser-known underworld beneath Prague’s historic streets with a visit to the cellars of the Mů처ská Sewage System, now largely abandoned and sealed off to the public. Once part of the city’s medieval sanitation infrastructure, these labyrinthine tunnels chronicle centuries of hygiene challenges and engineering effort. While not fully open to the public, nearby guided tours reveal the eerie stillness and hidden heritage of this underground maze—an unexpected refreshing contrast to Prague’s bustling above-ground charm.

3. Krysí Kášno: The Cliffside Village You Can Only Reach Hiking

Perched dramatically on a rocky outcrop above the Vltava River, Krysí Kášno is a tiny, elusive village accessible only by a steep, winding footpath. This forgotten settlement, dotting jagged cliffs and terraced gardens, feels like stepping through time—untouched, remote, and steeped in solitude. With no cars allowed and limited tourist signage, visiting Krysí Kášno offers a serene escape from the crowds, plus sweeping views of Prague’s skyline from a vantage few ever enjoy.

These hidden gems provide not just architectural beauty but a doorway into centuries of hidden knowledge and curiosity, perfect for lovers of history and the occult.

5. The Little Alchemist’s Garden: An Urban Outdoor Sanctuary
