Fort Carré is a 16th-century star-shaped fort of four arrow-head shaped bastions, that stands on the outskirts of Antibes.
The Romans probably built the first fortifications at Antibes. In 1553, a tower called la tour Saint-Florent was built around a pre-existing chapel. Henry III had four bastions added in 1565, whereupon it became Fort Carré (the squared fort).
In the 1680s, Vauban strengthened Fort Carré, adding traverses to protect against ricochet fire and exchanging the stone parapets, which were liable to scatter deadly splinters when hit by shot, for brick ones. Vauban also enlarged the embrasures and added outer walls to the fortification.
Later, the fort's design was modified to take eighteen cannon. The entrance to the fort is through a triangular work that protrudes from the walls, and which is loopholed and pierced by a heavy wooden door. From here, there is a narrow bridge that leads into the fort itself via the flank of one of the arrow-headed bastions. Inside, there are barrack buildings for officers and men as well as the ancient chapel, which has been preserved through the successive stages of military development of the site.
In addition to improving the defences of Fort Carré, Vauban fortified Antibes itself, adding a land front of four arrow-headed bastions around the town, as well as seaward fortifications, including a bastion on the breakwater closing the harbor.
During the French Revolution, Napoleon Bonaparte was briefly imprisoned here. In July 1794, after the violent overthrow of Robespierre, General Bonaparte was detained as a Jacobin sympathizer and held in Fort Carré for ten days. His friend and political ally, Antoine Christophe Saliceti, secured his release. Then in 1860, the fort played an important role when France annexed Nice.
Today Fort Carré is open to the public.
References:The Amphitheatre of the Three Gauls was part of the federal sanctuary of the three Gauls dedicated to the cult of Rome and Augustus celebrated by the 60 Gallic tribes when they gathered at Lugdunum (Lyon). The amphitheatre was built at the foot of the La Croix-Rousse hill at what was then the confluence of the Rhône and Saône.
Excavations have revealed a basement of three elliptical walls linked by cross-walls and a channel surrounding the oval central arena. The arena was slightly sloped, with the building"s south part supported by a now-vanished vault. The arena"s dimensions are 67,6m by 42m. This phase of the amphitheatre housed games which accompanied the imperial cult, with its low capacity (1,800 seats) being enough for delegations from the 60 Gallic tribes.
The amphitheatre was expanded at the start of the 2nd century. Two galleries were added around the old amphitheatre, raising its width from 25 metres to 105 metres and its capacity to about 20,000 seats. In so doing it made it a building open to the whole population of Lugdunum and its environs.
