Ла-Буреба
In 1213, count Álvaro Núñez de Lara, married to Queen Urraca's niece, Urraca Díaz de Haro gave her several properties in La Bureba, with which she later founded, in 1222, the Monastery of Santa María la Real in Vileña, entrusting its governance to the Cistercians. Although she was not the abbess of this monastery, she became a nun and was buried in a sepulcher made of stone placed in the presbytery of the church at the monastery that was transferred subsequently to the Museum in Vileña after the monastery was destroyed by fire in 1970 and then again to the Museum of Burgos.
