It is a tower 'de armas', which was manned by a commander, a gunner and four soldiers to protect the bay of Teulada from possible attacks by North African pirates. It was in visual contact with the other towers: Sant'Isidoro, Piscinnì and Malfatano to the southeast and Porto Scudo to the south-west.

It underwent several restorations over the years, but remained garrisoned until 1843, when it became an anti-smuggling checkpoint. Its first commander was Costantino Melis, who held this position from 1603 to 1614.

Architecturally, it is very similar to the nearby tower of Piscinnì: cone-shaped, with a height of 9.80 metres and the main chamber standing at about 4.5 metres above the ground.  

The chamber is vaulted with a pillar in the centre and mouldings on the sidewalls; it features wooden floors and a trunk, a fireplace, an access hatch to a cistern and a staircase to the terrace. A parapet with embrasures and battlements is visible at the top. The external staircase was built after 1843, when the tower became a strategic post for combating smuggling instead of guarding against pirates.
