Castelló d’Empúries has kept the charm of its mediaeval past and the vestiges of the period which was really its golden age. In the 11th century the Counts of Empúries moved the county capital and their residence from the Greek and Roman town of Sant Martí d’Empúries to the “Vila Castillione” and new county town: Castelló d’Empúries. The official consecration of the church of Santa Maria also dates from this century. Its Gothic nave and side aisles were built towards the end of the 13th century. The façade, with its magnificent main door, dates from the start of the 15th century and the Mare de Déu de la Candelera altarpiece from the end of the same century.
Also preserved almost intact from the mediaeval period are the belfry in the tower (Romanesque and transitional), the baptismal font (11th century), the Gallarda gateway, the base of the Muralles (town walls) and even the Pont Vell (Old Bridge) which dates from the end of the 13th century. The historic centre of the town still features arcaded squares and the street names reflect the activities that took place in them: Carrer del Bordell (brothel), Plaça de les Cols (cabbage), del Vi (wine), de l’Oli (oil), de les Gallines (hens), etc. Districts in the town included the Call Jueu (Jewish quarter), the Temple, named in honour of the Knights of the same Order, Botxí (executioner), Sant Llàtzer, etc.
Many other buildings were begun in the mediaeval period but only completed in the 17th and 18th centuries. They include numerous convents and civic buildings.
