After the war, Rostock – now in the German Democratic Republic – became East Germany's largest seaport. The state expanded the national shipyards in the district of Warnemünde. The city's population, boosted in part by resettled ethnic German refugees who had been expelled from territories in the east, increased in the GDR years to a peak of 260,000. Following the reunification of Germany in 1990, Rostock lost its privileged position as the No. 1 port of the GDR, and the city's population declined to about 200,000. However, after 2006, the population increased again. Today, Rostock and Warnemünde are significant tourist destinations on the Baltic Sea.
