seamarks
Coastal guidance structures
Seamarks are objects or structures visible from the water that help sailors navigate—lighthouses, buoys, distinctive coastal features, or prominent buildings.
Anything that serves as a reference point for those at sea qualifies: The church steeple served as a seamark for generations of fishermen returning to harbor.
