Prague’s cobblestone streets are alive with history and intrigue. While the city’s medieval charm leads the way, another, less visible presence lingers in the shadows—alchemy. Under Emperor Rudolf II, Prague became a hub for alchemy—a blend of plant medicine and chemistry that sought to uncover the universe’s secrets, including the Philosopher’s Stone. Join us on a tour of Prague’s most magical sites and discover the hidden secrets.
1. The Faust House
Shrouded in mystery and legend, the Faust House is a significant site in Czech folklore. The story goes that a poor student found an abandoned mansion filled with coins—courtesy of the Devil himself. Over time, alchemical symbols and macabre artifacts, thanks to the infamous resident Karl Jaenig, filled the house. Today, it’s part of the Faculty of Medicine at Charles University, standing as a haunting reminder of Prague’s dark past.
2. House at Donkey in the Cradle
This historic site was once home to Edward Kelley, a renowned alchemist who reportedly discovered a manuscript detailing the Philosopher’s Stone. Kelley’s experiments here fueled rumors of the Philosopher’s Egg, the first step in creating the Stone. Although visitors can only view the house from the outside, Kelley’s alchemical legacy continues to captivate onlookers.
3. Speculum Alchemiae
Discovered in 2002 after a flood revealed hidden tunnels, Speculum Alchemiae offers a glimpse into Prague’s alchemical past. Linked to Emperor Rudolf II, this underground laboratory is filled with dried herbs, flasks, and a mortar and pestle. Visitors can explore the tunnels and even purchase homemade elixirs, stepping into a world where science and magic intertwined.
4. Museum of Alchemists and Magicians of Old Prague
Delve deeper into Prague’s alchemical connections at this museum, where stories of medieval alchemists come to life. Wax figures in period attire recreate ceremonies and practices, while the attached alchemical lab pub, Kellyxír, serves beverages evoking the magical spirits of old.

5. Prague Castle, Mihulka Tower
Known as the Powder Tower for its gunpowder storage, Mihulka Tower also served as a dungeon and alchemical lab. Emperor Rudolf II invited famed alchemists like Edward Kelley and John Dee to refine their skills here, seeking to transform lead into gold. The tower stands as a testament to Prague’s alchemical ambitions.
6. Mysterium Tours
Experience Prague’s mysteries with Mysterium Tours’ “The Black Angels of the Prague Castle” and “Dark Shadows of the Old Town.” Guides in Gothic costumes lead nighttime tours by lantern light, evoking the era when Emperor Rudolf II’s alchemical interests shaped the city’s history.
7. The Charles Bridge, Old Town Bridge Tower
Constructed under King Charles IV’s guidance, the Charles Bridge aligns with alchemical and astronomical principles. Built on July 9, 1357, at 5:31 a.m., the bridge’s construction time forms a palindromic number believed to harness planetary powers. Explore underground tours to view the bridge from a unique perspective.
8. Rabbi Judah Loew’s Headstone
Rabbi Judah Loew, a scholar and mystic, is credited with creating the Golem—an alchemical creature made from clay to protect Prague’s Jewish community. The Golem’s story is linked to Kabbalah and alchemical practices. Visit Rabbi Loew’s tombstone at the Jewish Museum in Prague to honor his mystical legacy.
9. Petrin Hill
From the highest point in the city, Petrin Hill’s layout forms sacred geometry. The cross-shaped arrangement of buildings, streets, and churches reflects Prague’s deliberate design to channel alchemical energies, solidifying its status as an alchemical capital.
10. The Astronomical Clock
The Astronomical Clock, a marvel of medieval engineering, is steeped in superstition. Legend says the city’s fate is tied to the clock’s functionality. Its intricate details, including animated figures representing fortune and misfortune, add to its mystical allure. The clockmaker’s eyes were allegedly gouged out to prevent him from replicating this masterpiece elsewhere.
11. Johannes Kepler’s Home
Though not an alchemist, Johannes Kepler’s astronomical work laid the foundation for the synergy between science and astrology. Emperor Rudolf II enlisted Kepler’s expertise to advance his court’s alchemical and astrological pursuits. Kepler’s home remains a significant site in Prague’s history of scientific and mystical exploration.
