The Royal Dike

The Royale and Taff dikes are two artificial dikes, dating from the 17th and 18th centuries. They separate the fossil dune ridge from the more recent dunes. Their presence facilitated the creation of a vast polder, forming an extremely interesting grassland landscape.

Walde Lighthouse

Somewhat "lost" on the wild beach of Marck, the Walde lighthouse is unique in France for its original structure and iron construction. No longer useful for navigation, it was permanently decommissioned on July 4, 2001. It remains, however, one of the last remaining metal sea lighthouses in France.

It also remains an important point from a cartographic perspective, as it marks the boundary between the English Channel and the North Sea. It is also a meeting point for a colony of seals and seabirds: it's best to keep your distance, including dogs on leashes, and bring good binoculars.
