This pavilion housed the Consulate of the Sea, which was formed in 1283 and governed all maritime and business-related issues, and is made up of four parts: a basement, the ground floor and two upper floors. The design of the pavilion started out as gothic but ended up as renaissance, and, whilst the differences are not always visible on the inside of the building, the two styles are evident on the facades of the building which look out over the Plaza del Mercado and the Orange Garden. Clear differences can also be seen in the architecture of the windows of the ground, first and second floors.
