There is a legend that the bishops banished from Africa to Corsica in 484 by Hunneric, Arian King of the Vandals, built with their own hands the primitive cathedral of Ajaccio. The present cathedral, dating from 1554 to 1593, owes its construction to the initiative of Gregory XIII, who while still Ugo Buoncompagni, spent some time at Ajaccio as papal legate.
The legend of bishops being exiled and building a primitive cathedral is connected to the construction of the present cathedral in Ajaccio, which was built later (1554-1593) under the initiative of Gregory XIII who visited Ajaccio as a papal legate.
