The Dominican monastery of St. Catherine in Stralsund was founded by Jaromar II, Prince of Rügen Island, in 1251.  In 1951 the German Museum of Oceanography was founded in 1951 and established in the monastery.
      In 2001 Germany issued a stamp which commemorated both the 750th anniversary of the founding of the monastery and the 50th anniversary of the founding of the oceanographic museum. A view of the monastery church is set against a background of a portion of a map of the Atlantic Ocean.
