Torre Bianca di Porto Ferro

Built in the 16th century in dry masonry composed of limestone rocks and lime mortar, the White Tower of Porto Ferro has a height of approximately 6 meters, with a diameter at the base of approximately 12 meters.

It was built for military purposes but was mostly used as a refuge for fishermen.

The Torre di Airadu (or Torre Radu, Torre Bianca or Torre di Mezzo) is a tower in the bay of Porto Ferro (Sassari); when they joined the Torre Negra and the Torre di Bantine Sale, it was one of the three towers that dominated this coast and protected the island from Saracen incursions during the reign of Filippo II.

It is a classic "senzillas tower" located on the road between the other gates of Porto Ferro[1]. Erected in the 16th century, it is made of a compost heap of calcareous rock and calcareous malt; it is about 6 meters tall, has a diameter at the base of about 12 meters and remains intact on the inside of the interior[2]; the only entrance door is a 1.5-3 meter high post entrance from where you can access the interior, delimited by a volta on the dome with a central view and surrounded by various niches and holidays.
