Castello di Salvaterra, Medieval castle in Iglesias, Italy

Castello di Salvaterra, also known as Castello di San Guantino, stands on the hill of Salvaterra above Iglesias. A 1358 drawing shows a quadrangular fortress with three towers: two on the sides and one in the centre, the latter containing the entrance. In the 19th century it was joined to a neo-Gothic villa and a glass factory.

The fortress was built in the late 13th century under Pisan rule and was captured by Aragonese forces in 1324. After this conquest, the structure underwent several modifications that shaped its later form.

The castle exemplifies medieval military design that played a key role in Sardinian defense strategies. Visitors can still observe the solid construction and defensive features that made this structure important for the region.

The site is accessible to visitors with maintained paths to explore the building and its layouts. It is advisable to wear comfortable shoes since some areas have uneven ground.

Until 1905, a commemorative inscription from 1325 was visible on the castle gate's lintel, recalling the period when Berengario Carròs held the fortress. The 1358 drawing shows the original quadrangular plan with three towers: two on the sides and one in the centre with the entrance.
