Hindenburgdamm, Sylt, Schleswig-Holstein, Germany
The causeway, which bears the Weimar Republic Reichspräsident Paul von Hindenburg's name, has interrupted the tidal flow, which until the causeway's appearance had flowed freely between Sylt and the mainland. This change in tides, it is believed, is part of what has led to the loss of a certain amount of land at Sylt's southern end.
