Castello dell'Asinara, Medieval fortress in Porto Torres, Italy.
Castello dell'Asinara is a medieval fortress perched on Asinara Island off the coast of Porto Torres. Its walls are built from granite blocks that blend into the rocky landscape, creating a sturdy structure adapted to the harsh island environment.
The fortress was built during the medieval period to control the straits and maritime passages in this region. It served as a defensive position through different eras, protecting against threats from both sea and land.
The name comes from Asinara Island, where the fortress is located. Today it functions as a heritage site within a national park, drawing visitors interested in exploring both the structure and the island's natural environment.
The fortress is located on a protected island and cannot be visited freely at all times. Before planning a trip, check if guided tours are available or if access is restricted during certain periods.
The fortress was part of a larger network of coastal towers and fortifications around the Gulf of Asinara. Lookouts could exchange visual signals between these positions to quickly share information about ships and potential dangers.
