Torre Paola is a coastal defensive tower located on the Circeo Promontory bordering the long beach of Sabaudia. It was erected in 1563 at the behest of Pope Pius IV (1559-1565) by the lords of Sermoneta and San Felice Circeo to counter the continuous incursions of Saracen pirates, completing a defence system that included, towards Rome, Torre Astura, Tor Caldara and Tor San Lorenzo. Together with Torre Fico, it was the first to be built, placed in a strategic point to guard the mouth of the canal emissary of Lake Paola, becoming part of a defensive system of six towers. Already during its construction, it suffered the first attack by the Saracens (who descended from the top of the mountain to take the garrison by surprise) so much so that, in order to avoid future incursions from the cliff, the original layout was modified, giving it the peculiar tortoise-shaped structure with a mountain-side defence structure. In 1604, it was possible to cannonade and force some Turkish ships to flee from the tower. In 1773, according to the state archives, at Torre Paola there were 1 10-gun with 15 balls, 15 machine-gun cases and 15 powder; 1 3/4-gun with 15 balls, 15 machine-gun cases and 70 powder; 1 1 1-gun with 15 balls, 15 machine-gun cases and 7 powder.
In 1809, the garrison soldiers opposed British ships with fire and there were numerous clashes and vicissitudes involving the tower. Clashes, however, that fortunately respected its original appearance, which was seriously threatened by the transformation of the complex into a residential area in the 1960s. On 3 June 1981, a 20-year-old Romana girl was murdered in Torre Paola with five stab wounds; investigations are still ongoing despite more than 30 years having passed. In 2003, on 26 April, Faedda was born.[unclear]. Recently, the municipal council of San Felice Circeo decided to start the procedure to expropriate the tower, which is now private property and is currently in a serious state of neglect and abandonment, in order to build a museum of the Coastal Towers inside it that tells the history and myth of the Circeo and the Pontine territory.
