Ajaccio is a French commune, prefecture of the department of Corse-du-Sud, and head office of the Collectivité territoriale de Corse. It is also the largest settlement on the island. Ajaccio is located on the west coast of the island of Corsica, 210 nautical miles southeast of Marseille.
The original city went into decline in the Middle Ages, but began to prosper again after the Genoese built a citadel in 1492 to the south of the earlier settlement. After the Corsican Republic was declared in 1755 the Genoese continued to hold several citadels, including Ajaccio, until the French took control of the island.
The inhabitants of the commune are known as Ajacciens or Ajacciennes. The most famous of these is Napoleon Bonaparte, who was born in Ajaccio in 1769, and whose ancestral home, the Maison Bonaparte, is now a museum. Other dedications to him in the city include Ajaccio Napoleon Bonaparte Airport.
