St. James in Prague: The gruesome story of the mummified thief’s arm

Hidden in the winding streets of Prague’s Old Town, not far from the Old Town Square, lies the basilica. St. Jacob (Kostel svatého Jakuba Staršího). It is famous for its magnificent Baroque furnishings and fantastic acoustics – but most visitors come for a far more sinister detail: a black, withered arm hanging from the ceiling by a chain to the right of the entrance.

The legend: A theft with divine consequences

The story behind this macabre exhibit takes us back to the year 1400. Legend has it that a thief sneaked into the church after evening mass to steal the precious offerings from the statue of the Virgin Mary.

When the thief reached for the Madonna’s jewelry, the unbelievable happened: The statue came to life and grabbed the thief’s arm so tightlythat he could no longer free himself. The next morning, the monks found the man frozen with fear. Since the statue would not release his arm, the butchers of the guild (who guarded the church) had no choice: they had to amputate the arm.

400 years of deterrence

As soon as the arm was severed, the statue let go. As a warning to all other potential thieves, the monks hung the arm on a chain. There it has hung for over four centuries – now completely mummified and blackened, but still clearly visible as a reminder of the importance of honesty.

What you shouldn’t miss in St. Jakob

Although the arm is the main attraction, the church has more to offer:

  • The tomb of Count Vratislav of Mitrovice: One of the most beautiful Baroque tombs in Bohemia. But beware: there’s also a gruesome story about a living burial here…
  • The organ: With over 8,000 pipes, it is one of the largest and most sonorous in the entire Czech Republic.
  • The baroque splendor: The ceiling frescoes and the 21 altars make St. Jakob one of the most magnificent churches in the city.

📍 Visitor Information

The church is located in the alley. Malá Štupartská. Entry is usually free, but be sure to check the opening hours (often only accessible during masses or concerts). You’ll find the arm on the right-hand side immediately after entering the church, if you look up.

Last but not least: St. Jakob displays the typical Prague blend of deep religiosity and morbid curiosity. A quick stop is definitely worthwhile – but keep your hands to yourself!
