The cathedral in the early days of the Reconquest was called "Església Major", then "Seu" (Sedes), and at the present time, in virtue of the papal concession of 16 October 1866, it is called the "Basílica metropolitana". It is situated in the centre of the ancient Roman city where some believe the temple of Diana stood. In Gothic times it seems to have been dedicated to the most Holy Saviour; the Cid dedicated it to the Blessed Virgin; King James the Conqueror did likewise, leaving in the main chapel the image of the Blessed Virgin which he carried with him and which is believed to be the one which is now preserved in the sacristy. The Moorish mosque, which had been converted into a Christian church by the conqueror, appeared unworthy of the title of the cathedral of Valencia, and in 1262 Bishop Andreu d'Albalat laid the cornerstone of the new Gothic building, with three naves; these reach only to the choir of the present building. Bishop Vidal de Blanes built the magnificent chapter hall, and Jaume of Aragon added the tower, called "Micalet" because it was blessed on St. Michael's day (1418), which is about 166 feet high and finished at the top with a belfry.
