What is the name of the wall built on the edge of the coastline?

The wall built on the edge of the coastline is known as a sea wall. This structure is specifically designed to protect the coast from the effects of wave action and erosion. By absorbing and reflecting the energy of waves, sea walls help maintain the integrity of the shoreline and prevent flooding in coastal areas. They are often constructed using concrete or rock and can be found in many coastal cities around the world. Their primary purpose is to provide a barrier against the forces of the sea, making them integral to coastal management strategies aimed at protecting vulnerable areas.
