Most of Spanish people linkk “El Pardo” Palace to the life of General Francisco Franco, died in 1973. But The Royal Palace of El Pardo, located just a few miles Outside Madrid is a magnificent jewel, started in XV century and it has been the vacational residence of two different dinasties of Spanish Monarchs: Austrias and Borbons.
Everything is very delicate and special inside, but to be honest, I think it is very difficult to find a larger collection for tapestries (many of them by Franciso de Goya) , coming form XVII and XVIII centuries.
I do recommend this visit.
