Castelló d'Empúries is a town and municipality in the Alt Empordà in Girona, Catalonia, Spain. It lies 9 km east of Figueres. In 1079, Castelló d'Empúries became the capital of the Empúries county due to the previous capital, Sant Martí d'Empúries, being too easily sacked by pirates. 1325-1341 saw a period of large expansion of this capital town, which ultimately ceased being the capital once the county joined the Crown of Aragon in 1385.
