The Gothic Chapel of the Virgin Mary in Prague’s Old Town Hall, an architectural rarity in Bohemia, boasts Gothic tracery windows and stone adornments. Built by Petr Parléř in the 14th century, it served as a sanctuary for city council meetings, prisoner rites, and royal masses. Despite facing destruction in the Hussite wars and deconsecration by Emperor Joseph II, it underwent significant renovations in the 19th century, including a neo-Gothic altar by Josef Mocker. Damaged during World War II, ongoing repairs saw its restoration, with restored elements returning in 2018. Now part of the Old Town Hall tour, it hosts occasional services and events.
