[1] The building was commissioned by local officials, the five consuls, and authorised by King Sancho, when the town formed part of the Kingdom of Majorca in the early 14th century.

It featured two semi-circular openings with iron gates on the ground floor and rows of pebbles, often found in Catalan architecture, fixed to the first-floor façade.

Three bronze hands, which recalled the three categories of society order under the ancien régime (the bourgeoisie, the professionals and the traders) were installed below the first-floor windows.

[4] Internally, the principal rooms include the wedding hall in the south-east corner of the building, which featured a ceiling decorated in the Hispano-Moorish style, which was created in the early 16th century.

[7] Another prominent room was the Salle Arago, which served as the council chamber for the city council and was decorated with early-20th century paintings by Henri Perrault, depicting Hannibal's crossing of the Alps in 218 BC,[8] the oath by John II of Aragon to protect Perpignan following the Catalan Civil War in 1473,[9] and the French victory at the Battle of Peyrestortes in 1793.
