All along the shore, you'll find such small towns built upon hills.
In times when danger could come from everywhere around, it was important to see ennemies before they could reach you..
Every house was built as / or / in a wall, every wall was thought as a protection, every street was supposed to be narrow and broad enough to stop an invasion, every gate was supposed to be closed as quickly as possible, every tower was used as watching place..
And , of course, the final goal, the castel , was supposed to protect eveyone if every other mean had failed..
Today, the castel is a museum.
The only invaders are tourists, and I'm afraid nothing can stop them!..
But let's be glad to live in peaceful times..
