The tower stands on the site of a Roman villa maritima once owned by Cicero.
The stone bridge connecting the tower to the shore was built by the Frangipane family to create an insular defensive stronghold.
Conradin of Swabia, the last Hohenstaufen claimant to the throne of Sicily, was betrayed at this location after his defeat.
The surrounding seabed contains remains of Roman fish ponds, or 'piscinae', which are occasionally visible from the surface.
During World War II, the area saw significant military activity due to its proximity to the Anzio beachhead landing zones.
The current structure is owned by the Italian Ministry of Defence.
Torre Astura is a fortified coastal tower connected to the mainland by a long, narrow stone bridge, situated on the Tyrrhenian Sea in Nettuno. Originally built in the 12th century by the Frangipane family, the structure incorporates ancient Roman ruins, including the foundations of a maritime villa. It served as a strategic military defensive point during the Middle Ages. In 1268, the Battle of Tagliacozzo concluded near here when Conradin of Swabia was captured after seeking refuge at the tower. The site is currently located within a restricted military zone, affecting public access. The surrounding waters are known for their submerged archaeological remains.
