The Lost Monastery of the Angels Hoz

Founded by Franciscan monks in 1231, the Monastery of Nuestra Señora de la Hoz was possibly rebuilt in the 15th century and remained inhabited until 1835, when it was abandoned. Today, the monastery ruins can only be accessed from the embalse de Burgomillodo, most of the year. The monastery is known for housing Nuestra Señora de los Ángeles de la Hoz. King Felipe II, a devout follower of the Virgin of La Hoz, finished the rebuilding and added a hostel after the monastery was destroyed in 1492. Although abandoned and in ruins today, the monastery still stands with three arches on its southern facade. Holes for windows, doors, and arched galleries can still be seen in these walls. Some coats of arms, both carved and painted, can still be seen.
