La Lonja was built to provide a location for trade and commerce in an era at the end of the 15th century when business was prospering in the city. Business deals were made in the Hall of Columns, otherwise known as the Hall of Trade, which, along with the tower, constitutes the main nucleus of the building. The third main element is the building that housed the Consulate of the Sea, with all areas being joined by the Orange Garden. Construction was carried out in four phases between 1482 and 1548.
