All Saints' Church is a chapel located in the Prague Castle complex in the Czech Republic. The site of the church was originally consecrated in 1185 and a Romanesque building built; the oldest parts of the current building date to a structure constructed by Peter Parler in the 14th century. Although originally free-standing, the church was badly damaged in a 1541 fire which engulfed the palace and church. Through subsequent successive rebuildings and enlargements, the church became physically integrated with the palace, specifically Vladislav Hall.
