Torre Paola, Medieval coastal tower in San Felice Circeo, Italy.

Torre Paola is a cylindrical tower of light grey and beige stone masonry standing on a rocky height above the Circeo Promontory, at the border with the beach of Sabaudia. Its weathered walls carry a small arched window, and the top is ringed by a projecting parapet on evenly spaced stone brackets, above which rises a low, irregular crown. The base rests directly on the rock, partly hidden by vegetation.

Torre Paola was built between the late 15th and early 16th century, together with Torre Fico, to guard the outlet channel of Lago di Paola. Attacked by Saracens during construction, it was modified with a tortoise-shaped defence on the mountain side. Pope Pius IV had it updated in 1563, and in 1604 it bombarded Turkish ships.

The tower was a key station in a network of coastal watchtowers that connected communities along the shore. Local people relied on these structures as symbols of their collective ability to defend themselves and protect the trade routes that sustained them.

Torre Paola stands near the Strada Torre Paola, at the border between San Felice Circeo and the Sabaudia beach, where the outlet channel of Lago di Paola reaches the sea. The tower sits on a rocky height above the shore, so the approach is on foot over uneven stone and vegetation.

The tower's plan was altered during construction after Saracens attacked from the mountain above, giving it a tortoise-like layout with defences facing the slope. In 1773 its armoury held three cannon of different calibres, with 15, 15 and 7 boxes of gunpowder recorded in the state archive.
