1. Historical Overview and Architectural Origins

Mihulka Powder Tower is the largest tower of Prague Castle’s northern fortifications. Its construction, attributed to the architect Benedikt Ried, exemplifies late Gothic military architecture. Standing 44 meters tall and 20 meters in diameter, Mihulka was conceived as a defensive bastion, boasting walls up to 3.5 meters thick and equipped with gun and cannon loopholes on its lower floors. Despite its formidable design, historical records suggest that Mihulka never saw direct military action (prague.cz).

2. Transformation Through the Ages

Changing Names and Functions:
Throughout its history, Mihulka has been known as the New Tower, Round Fort, Laboratorium, and Swedish Laboratorium. These names reflect its changing roles—from defensive bastion to alchemical workshop, gunpowder store, and later, a residence for cathedral staff. The current name, Mihulka, was adopted in the 19th century, referencing an earlier tower used for lamprey storage (the Czech word for lamprey is “mihule”) (prague.cz).

Military and Civilian Uses:
After its alchemical period, Mihulka became a gunpowder magazine in the 17th century. In 1649, a catastrophic explosion—caused by negligence during the Swedish occupation—severely damaged the tower. By the mid-18th century, Mihulka transitioned to civilian use, housing sacristans and cathedral staff (prague.cz).

3. Alchemy and the Rudolfine Era

During the reign of Emperor Rudolf II, Prague was a hub of mystical and scientific pursuits. Mihulka hosted some of the most enigmatic alchemists of the period, who sought the elixir of life and the transmutation of metals. The English alchemist John Dee, among others, is said to have worked here. The secrecy of their experiments was enforced due to the threat of the Inquisition and imperial interests. A 1609 document references a special corridor built to connect Mihulka with the emperor’s laboratory, highlighting the tower’s scientific significance (prague.cz).

4. Restoration and Modern Exhibitions

Restoration:
A major restoration in 1982 preserved Mihulka’s historical integrity and made it accessible to visitors. Stonework was stabilized, frescoes and architectural details were conserved, and the space was adapted for public exhibitions (Prague Castle official site).

Current Use:
Today, the tower houses a permanent exhibition curated by the Military History Institute. The display spans three floors and covers:

The history and evolution of Czech military technology
The legacy of the Castle Guard
Artifacts such as historical weapons, armor, and the post-1989 BMW K75 motorcycle
Insights into alchemy and bell-founding, including references to Tomáš Jaroš, renowned for the Singing Fountain and the Zikmund bell (prague.net).

5. Notable Historical Residents

Among Mihulka’s notable historical figures is Tomáš Jaroš, a distinguished bell-founder and gun maker who resided here in 1569. His work—the Singing Fountain and the Zikmund bell—remains central to Prague’s cultural heritage (prague.cz).
