Escoria Monastery is a world cultural heritage in Madrid. It is a huge monastery with royal style. In fact, it is also the Royal Mausoleum of Spain. There are many famous Spanish kings buried in it. However, the monastery is far away from the city. If time permits, I suggest you look at it. There are still a lot of Royal collections, very precious. Expensive.
Philip II, an emperor whose father did not like him, eventually created brilliance. His suburban palace and monastery were integrated into one building, showing that his decision to support Catholicism also led to a period of architectural style.
