"Built between 1482 and 1533, this group of buildings was originally used for trading in silk (hence its name, the Silk Exchange) and it has always been a centre for commerce. It is a masterpiece of late Gothic architecture. The grandiose Sala de Contratación (Contract or Trading Hall), in particular, illustrates the power and wealth of a major Mediterranean mercantile city in the 15th and 16th centuries." -http://whc.unesco.org
