The House of the Municipal Council of Castelló or medieval fish market, later became the headquarters of the City Hall. It retains the structure from the end of the 14th century (around 1393) with some renovation work carried out in the 18th century. Of particular note are the façade with its large embossed coat of arms, the interior space with gothic vaulted ceilings which has the emblem of the village in the key stone, and the side arches with columns and capitals.
