White stone markers

The public domain (dominio publico maritimo terrestre DPMT) has a very wide definition, including :-

1) the surf zone and the beach.

2)all areas where the sea waves reach or have reached in the worst known storms.

3)all areas where there is sand, shale or pebbles, whether or not it is built on or whether or not the waves ever reach there, up to a point where the effects of the coastal winds are negligible and the area is not necessary for coastal protection.

4) all areas reclaimed from the sea

Basically, public land, no building or private ownership.

Thank you very much for your very informative reply. Best wishes Stan.
