The name of the town comes from the word ‘escoria’ which means slag. That’s because of the old local foundry that used to be important for the town.
La Granjilla de la Fresneda, or just La Fresneda was a cottage of the king Phillip II in the environment of the Monastery of El Escorial. It was constructed between 1561 and 1569.
Beautiful Dome and architecture
the interior is even better! Incredible!
