I was at the beach, it was a bit cloudy and the sea had quite a few algae. According to my son, "the sea is disgusting," so I said to myself, why not go for a walk on the rocks? So I took him by the hand and we went. It's a breakwater made of rocks; it separates the shallow, swimmable beach from the deep part where yachts, container ships, etc. pass by. The nice thing is that there's a central concrete path and the rocks are on the sides, so there's no risk of falling. Those who prefer the experience of walking directly on the rocks can do that too. There are often fishermen or people who just lie there to sunbathe.
Typical are these kinds of stilt structures, called trabucchi. As you can see, they lower nets into the sea, then after a while they pull them up, catching shellfish and fish. If you zoom in on the photo, you can see the crabs caught, much to the delight of seagulls who get a snack. In some of these, it's possible to eat what has been caught. Needless to say, you have to book well in advance and the prices are also quite high.
A little house that honestly I don't know the purpose of, maybe for weather or tide measurements.
The rocks are the classic square stone blocks; however, at the end of the breakwater, they have this very strange shape, a kind of symmetrical three-pronged truncated form. I don’t know the name, but they're very unique.
And finally, the lighthouse at the end, clearly to prevent ships from crashing into the breakwater at night.
There's also a lighthouse in the water.
I walked around the lighthouse and then we went back.
