Giraglia

It consists of a cylindrical tower 25.80 metres (84.6 ft) high, with balcony and lantern, rising from the centre of the keeper's house.

It was one of a series of coastal defences constructed by the Republic of Genoa between 1530 and 1620 to protect against attacks by Barbary pirates.

The tower is owned by the French state and in 2008 was listed as one of the official Historical Monuments of France.
