St. Mary's is the church of the Council of the Hanseatic City of Lübeck. The brick basilica serves as a model for the Gothic brick style of churches in the Baltic region. For the first time, the Gothic cathedral style of France was adapted to the local brick.Numerous works of arts are to be found in St. Mary's interior: The Cross of Triumph by Gerhard Marcks in the high choir above the Swarte Altar from 1495 is as much at home here as the largest mechanical organ in the world. The well-known church musician and composer Dietrich Buxtehude was St. Mary's organist and work master from 1667 to 1707.The commemorative chapel in the south tower with its church bells possesses a unique expressive power. The bells plunged to the stone floor during the 1942 air raids. The Gothic brick basilica has a medieval painting, the largest peel of bells in Schleswig-Holstein and a carillon with 36 bells from St. Catherine's Church in Danzig.The two danse macabre windows take the motif and figures from the frieze of the Lübeck danse macabre burned in 1942.
