Fortresses, Castles & Palaces in Sardinia
Alghero Medieval Walls
One of the most striking and picturesque features in Alghero are the medieval walls surrounding the town’s historical centre. Canon and catapults, towers and forts along the way are a fascinating reminder of Alghero’s rich history. Like many places, these walls were built and then repaired and developed over the centuries. Alghero was a fortified Genoese port town as early as the 11th century. In the mid 1300s the Catalans repaired the walls, but much of what we see today was built in the 16th century by the Aragonese.


Aymerich Castle, Laconi
Set in a public park created in 1830 are the ruins of the medieval Aymerich Castle. Although much of what we see today dates to at least the 13th century, it is thought that there was an earlier settlement probably dating back to the 12th or even the 11th century. The castle was built to defend the borders of the Judicate of Arborea from the Cagliari Judicate. In the 19th century, when the ruling family of the fief of Laconi were living here, the castle was destroyed by fire. Visitors are free to walk among the ruins and see the vaulted arch entrance that is flanked by a rectangular tower, and the remains of the palace, with its Catalan-Gothic windows.

Torre di Longonsardo
Longonsardo Tower is at the northern end of the seaside resort of Santa Teresa Gallura, hence it is also known as Santa Teresa Tower. Set upon the rocks, it overlooks Sardinia’s northern coastline towards Corsica. The tower was part of a defensive system built in the 16th century for King Phillip II of Spain to protect Sardinia from looters. An impressive circular turret tower built using granite and with a height of 11 m, it is the largest defensive structure to be built by the Spanish in Sardinia. It has recently been repaired and refurbished, and is open to the public.
