Le Portel Customs Trail

Highlight • Trail

Here you have a beautiful view over the sandy beach of Le Portel. The village looks like a fortress fortified against the force of the sea.

Le Pêcheur & Solidarité en héritage

Highlight • Other

Gazing into space, you cannot miss the gigantic fresco of the fisherman of Boulogne-sur-Mer. Produced in the summer of 2018 on a bar of buildings on rue Bastié, the work of the German Hendrik Beikirch, who signs his work with the letters ECB, has just been rewarded.
