Groynes are a characteristic feature on many Baltic Sea beaches. They consist of wooden, stone or concrete structures that protrude into the sea perpendicular to the coastline. Their main function is coastal protection - they are intended to break the current, prevent sand erosion and thus preserve the beaches.
