The ‘white town on the sea’ is Germany’s oldest seaside resort, founded in 1793 by Mecklenburg duke Friedrich Franz I, and was fashionable throughout the 19th century as a playground of the nobility. You won't be able to miss the five gleaming white, heritage-listed buildings of the Grand Hotel Heiligendamm (www.grandhotel-heiligendamm.de) perched nearly on the beach.
