Among the square's landmarks is the cloth hall, which was originally designed in the 14th century as a center for cloth trade. It was gutted by fire in 1555 and rebuilt in the Renaissance style by Giovani il Mosca from Padua. The arcades were added in the 19th century. The ground floor is continually used for commerce with its many souvenir shops and cafés; upstairs houses the Gallery of the National Museum. Another landmark is St. Mary's Basilica with its Altar by Wit Stwosz, a Brick Gothic church built in the 14th century on the ruins of an earlier church destroyed by the Tartar raids of 1241. In the vicinity of the Market Square one can listen to the heynal, which is played each hour from the highest tower of St. Mary's Basilica. Other landmarks include the Church of St. Adalbert, Town Hall Tower and the Adam Mickiewicz Monument.
