You can access the Consulate of the Sea (Consulado del Mar) by exterior stairs located in the orange-tree patio. This part of the edifice, with a Renaissance style, was built at the beginning of the 16th century.
This room, with the famous Golden Chamber (Cámara Dorada), was a meeting place. It was covered by the beautiful wooden coffered ceiling remaining from the old Casa de la Ciudad (City Hall), now vanished.
The Trade Court used to meet on the ground floor to solve problems related to maritime trade.
