The original church was built at the end of the 14th century, and the Czech religious reformer Jan Hus was a regular preacher here from 1402 until his exile in 1412. Here he gave the mass in "vulgar" Czech—not in Latin as the church in Rome demanded. After the Thirty Years' War in the 17th century, the chapel fell into the hands of the Jesuits and was demolished in 1786. Excavations carried out after World War I uncovered the original portal and three windows; the entire
church was reconstructed during the 1950s. Although little remains of the first church, some remnants of Hus's teachings can still be read on the inside walls.
