The beacon of Sa Punta de Sa Torre was installed in 1993, in order to facilitate the entrance of the fishing boats.
The Portopetro Fortress is just a few meters far from “Sa Torre d’en Bossa, the popular name, built 1627, was rebuilt over an ancient tower, probably from the Islamic era, and it is located near the sea on land covered with pine forest. Its construction was a mixture of lime, sand and inside was bleached, the ceiling was made in seas, formerly was also bleached. The building had a ground floor, a second floor and a terrace and with 10 cm thick walls. It seems that there was a ladder inside with at least six or seven steps. The defence consisted of a valley in front of the entrance and had twelve slots on two different levels and distributed in different parts of the facade. It is believed that the terrace had access through a spiral staircase, missing in the ruins. A reform which consisted of reducing the ground floor was made at the end of the 17th century. The Portopetro Fortress is one of the most beautiful of our coast. In its surrounding you can find Caló de Sa Torre and Caló dels Homes Morts, two coves of fine sand and crystal clear waters, and from where you can enjoy a wonderful view of Portopetro bay.
