Why were the groynes built to protect the Cape Hatteras lighthouse?
By 1935, erosion was threatening the Cape Hatteras lighthouse so much that the water was actually reaching its base. The groynes, dikes and breakwaters were an attempt to hold back the erosion process. The groynes proved ineffective so the tower was abandoned and a functional light placed on a steel tower further inland from the shore. After a few years, wooden revetments, a more effective method for erosion control, helped reclaim some of the shoreline.
