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.
The first lighthouse built at Cape Hatteras was built in 1803, but the current Cape Hatteras lighthouse was built in 1870.
The current tower was first lit in 1870.

Ocracoke Lighthouse is owned by the United States government and is managed by the National Park Service. It is located in Ocracoke, North Carolina, and is part of the Cape Hatteras National Seashore. The lighthouse, which was built in 1823, is the oldest operating lighthouse in North Carolina. Public access to the lighthouse grounds is allowed, but the interior is not open to the public.
The Cape Hatteras Lighthouse, originally built in 1803 and later reconstructed in 1870, cost approximately $75,000 at the time of its construction. The lighthouse was moved in 1999 to prevent erosion from the encroaching Atlantic Ocean, a project that cost around $12 million. This relocation was necessary to preserve the historic structure and ensure its continued operation as a navigational aid.
For the safety of mariners and maritime shipping.
The sea defenses at Mappleton in the UK were built in 1991 as a response to coastal erosion threatening the village and its farmland. The defenses consist of rock groynes and a mass concrete seawall to protect the coastline from erosion by the North Sea.
