1991. They were built to protect the town from the severe sea erosion.
The population of Mappleton is 249.
why do people go to mappleton ?
there has been a sea wall built out to sea, but this has increased erosion ferther down the coast.
Mappleton is being protected because it has the main b1242 road passing it and this road links up to the main coastal towns such as tun stall and wither sea. Further north and south of Mappleton is not being protected because the north and south of Mappleton is surrounded by cheap farmland, and it would cost a lot to protect it.
