Beautiful vault built in granite ashlars in the 16th century as a refrigerator, served as a kaolin rot, the white clay used for the manufacture of earthenware in the nearby factory of Juan Falcó.
Abandoned at the closure of the factory, it has been recently restored by an employment workshop of women masons, financed by the unemployment office and town hall.
Reopened in 2007, today is the headquarters of the Museum of Ceramics and Glass of Valdemorillo, a museum of industrial archeology, unique in the Community of Madrid.
In it, you can see more than 100 pieces of porcelain, fine earthenware and glass made during the nineteenth and twentieth centuries, in the old ceramic factory. From fragments of Roman sigilata earth, that tells us from ancient ceramic tradition to electrical isolators, passing through plates and jars of fine earthenware, and royal tableware for Alfonso XII and Alfonso XIII. These were the first porcelain laboratory and the first fire resistant glass in Spain. A pioneer factory in many fields and worthy of numerous prizes.
