This third section of the coastal trench recovered by the curators of the Park is, compared to the others, the most unique. Here, there is no fortified post but a walkway defended by a wall about 1.30 m high. Looking closely at the stones used to raise this defence post, you can see that the work was done in several stages without paying too much attention to the strength of the wall, unlike the fortified points.
To access this walkway, which is higher than the path, it is necessary to pass through the opening which is still clearly visible and walk uphill for a few meters, with the defensive wall on your left characterized in this case by loopholes.
