By the end of the Second World War many German parishioners of St. Mary 's fled westwards , and also the parament treasure was evacuated to the west . In March 1945 Poland began expelling the remaining ethnic Germans in the city even before the border changes promulgated at the Potsdam Conference assigned the city to Poland . Most of St. Mary 's surviving parishioners wound up in the British occupation zone in northern Germany . Lübeck became a center for exiled Germans . All property of St. Mary 's Lutheran congregation in Danzig ( now Gdańsk ) was expropriated and its cemetery despoiled . However , two unsmelted bells of St. Mary 's , dating from 1632 and 1719 , later were found in the so-called Hamburg bell cemetery ( Glockenfriedhof ) . Of the prewar chimes , there still exist two bells , after restitution to the congregation loaned by its presbytery exiled in Lübeck to other congregations in northern Germany . '' Osanna '' from 1632 can be found in St. Andrew 's Church , Hildesheim , and '' Dominicalis '' from 1719 can be found under the name '' Osanna '' in St. Mary 's Church , Lübeck , both in Germany . '' Dominicalis '' is used by the congregation of Lutheran St. Mary 's Church , and the parament treasure is on public display
