The Czech town of Děčín enjoys a pastoral setting amid green hills. The 13th-century king of Bohemia Ottokar II invited northern neighbors to settle here, forever giving the town a German flair. Though the 1945 Potsdam Agreement expelled postwar Germans, Děčín embraces its heritage in many of its architectural treasures, including its namesake castle and the 1906 buttercream- and azure-colored synagogue, the only surviving structure of its kind in the former Sudetenland. Děčín’s elegant beauty was inspiration for Polish composer Frédéric Chopin.
