Before it became the idyllic promenade it is today, the coastal path was known as the customs path. It originated at the end of the 18th century and was used for surveillance missions: this passage running the length of the sea, unobstructed and with few facilities, enabled the coastguards to keep an eye on the horizon and move quickly from one point to another. The customs path was strategic, as it enabled the coastguards to cross cliffs and rocky escarpments. All along the way, gabion huts were set up as surveillance posts.
