The small Gothic saint Martin church is the only remaining part of the oldest Piast's castle in Wroclaw (The Silesian Piasts were the oldest line of the Piast dynasty that gave Poland its first kings). It was created in 80's of the XIII century surely as a church of the monastic foundation of Henry Probus (that is Right, the same who financed saint Cross and saint Bartholomew collegiate church) under the call of the Holiest Virgin Maria, and also a funeral chapel. During the time of the World War II it was severely (in approx. 80%) destroyed. The outlines of walls of the Piast's castle can be seen around and nearby stands at present a monument of pope John XXIII.
