Church of Our Lady Assumed into Heaven 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). On every hour, a trumpet signal—called the Hejnał mariacki—is played from the top of the taller of St. Mary's two towers.
