From The Guardian: Oostduinkerke on the West Flanders coast is the only place in the world where you will still see the 500-year-old tradition of fishermen trawling for shrimp on horseback
From UNESCO: Shrimp fishing on horseback in Oostduinkerke. In Oostduinkerke, shrimpers mounted on horseback drag a net through the surf to catch shrimp. A good knowledge of the sea and the sand strip and a close relationship with one's horse are essential. The tradition gives the community a strong sense of collective identity and plays a central role in social and cultural events, especially the two-day Shrimp Festival. Twelve households, each with its own speciality, are active in shrimp fishing. Knowledge is handed down from generation to generation, with experienced shrimpers demonstrating their fishing techniques to beginners.
