Giraglia

Giraglia is a French island at the northern tip of Corsica in the Mediterranean Sea, known for its powerful lighthouse and for the Torra di Giraglia, a Genoese tower, both of which are official historical monuments of France.
The island is part of the commune of Ersa, but there are no settlements on the island. The closest settlements are Tollare, Ersa commune, and Barcaggio, Rogliano commune, on the main island of Corsica.
The Lighthouse.
The Giraglia Lighthouse is an active lighthouse located on Giraglia Island, about one mile off Barcaggio on the northernmost tip of Cape Corse. The lighthouse was first constructed in 1573 by the Genovese and has been rebuilt several times since. The current lighthouse was approved in 1838 based on a proposal by Léonce Reynaud and was inaugurated on January 1, 1848. It consists of a cylindrical tower high, with balcony and lantern, rising from the centre of the keeper's house. Initially the light was a flash every 30 seconds, but since 1904 it is a white flash every 5 seconds. The lighthouse is fully automated and controlled by the Marine nationale in Bastia.
Torra di Giraglia.
Construction of this tower began in April 1584. 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.
