Located close to Prague Castle, this fascinating museum explores the legends surrounding Emperor Rudolf II, who transformed Prague into a European center of alchemy during the late 16th century. Fascinated by science, mysticism, and the search for the philosopher’s stone, Rudolf invited scholars, astronomers, and alchemists from across Europe to his court in Prague.

Today, visitors can step into reconstructed laboratories, mysterious chambers, and secret passageways that recreate the atmosphere of this extraordinary period.

2. Speculum Alchemiae

Many tourists walk right past this building in Old Town without realizing what lies underneath.

Hidden beneath an ordinary historic building lies a fascinating network of chambers, workshops, and passageways connected to Prague’s long tradition of alchemy and mysticism.

Unlike many modern museums, Speculum Alchemiae feels remarkably authentic. Visitors descend into atmospheric underground rooms where alchemists are believed to have experimented with potions, elixirs, and the legendary philosopher’s stone centuries ago. Guided tours reveal fascinating stories about secret tunnels, mysterious symbols, and Prague’s reputation as a center of occult science during the reign of Emperor Rudolf II.

This museum turns those legends into interactive exhibits with sound effects, projections, and life-size figures.

Visitors walk through dimly lit rooms that recreate famous hauntings and historic crimes. Guided night tours are the main draw, because actors sometimes appear as “ghosts” to tell the stories in character. It’s more theatre than traditional museum, which is exactly why most tourists remember it.
