Lonja de la Seda
Not a church or a castle, but a former silk trade market, Lonja de la Seda is the place where merchants met for negotiations and closed deals. It is considered the result of the prosperous economic position of Valencia during the 15th Century.
Local industries, especially textiles, developed greatly during that time and the city became an important commercial center, where merchants from all over Europe came. La Lonja was a veritable trade temple of the Middle Age.
In 1996 it was declared a UNESCO World Heritage Site.
