Forte Filippo is the sentinel that dominates the entire bay of the old port. Just before arriving in the town, a small asphalt road will take you to the top. Go slowly and pay close attention to vehicles coming in the opposite direction! The road is very narrow and winding. Alternatively you can reach it with a nice half hour walk! The view you will enjoy in the last stretch will repay you for the effort. Fort Philip is a coastal fortification built in 1558 to improve the defensive system of the State of the Garrisons. Its name was chosen in honor of King Philip II of Spain. The Fort was built with four bastions and is deeply embedded in a moat carved into the rock. The only access point is represented by a drawbridge. You can only visit the perimeter, as the various buildings inside have been used as homes, but it is still worth it: the walkway on the walls is very suggestive. A path leads to the Torre del Mulinaccio. Originally it too was part of the defense system. It was then transformed into a windmill. The structure almost entirely collapsed, following the definitive abandonment of the mill. The panorama of Feniglia that can be enjoyed from here is worth a visit.

It was built by the Spaniards in the second half of the sixteenth century, due to its location it constituted one of the strategic points of the entire defensive system of the State of the Garrisons. Its shape is a six-pointed star. The entire structure is surrounded by a moat and the access door is preceded by a stone bridge which replaced the ancient drawbridge in modern times. The natural lighting of the internal environments is provided by a hexagonal-shaped opening that opens in the center of the terrace on the top of the Fort. Inside, exhibitions and cultural events are held. Its visit is permitted from May 1st to June 30th on weekends and from July 1st to September 30th every day. The entrance ticket costs 2 euros. From 1 October to 31 December visits are permitted upon request from the municipal administration. It can be reached by taking the panoramic road, leaving the town of Porto Ercole behind you, after a couple of kilometers you will come across a deviation to the right for Forte Stella. You can admire a wonderful panorama from a turtle-shaped island right below us.
