Saint Mary's Basilica is a Brick Gothic church adjacent to the Main Market Square in Kraków, Poland. Built in the 14th century, its foundations date back to the early 13th century and serve as one of the best examples of Polish Gothic architecture. Standing 80 m (262 ft) tall, it is particularly famous for its wooden altarpiece carved by Veit Stoss (Wit Stwosz). Some of its monumental polychrome murals were designed by Poland's leading history painter, Jan Matejko (1838–1893). In 1978 it became a UNESCO World Heritage Site alongside the Historic Centre of Kraków.

Brick Gothic is a specific style of Gothic architecture common in Northeast and Central Europe especially in the regions in and around the Baltic Sea, which do not have resources of standing rock. The buildings are essentially built using bricks. Buildings classified as Brick Gothic are found in Belgium, Netherlands, Germany, Poland, Lithuania, Latvia, Estonia, Kaliningrad, Denmark, Sweden and Finland.
