Castle of San Servando
Its origin dates back to the Arab period, a fact of course and proved, but there is no documentary evidence. We have to go back to the years after the Reconquista to have punctual data on the fortress. On March 11th, 1088 the Monarch Alfonso VI founded a monastery dedicated to the Saints Servando and Germano, providing of important donations and privileges.
The monks were forced to leave the monastery between 1099 and 1010, due to the constant Muslim attacks facilitated by their situation outside the walls. Queen Urraca ceded the building in 1113 to Archbishop Don Bernardo, belonging to the cathedral at least until the beginning of the 13th century. From this time until the end of the 14th century we do not know the avatars suffered by the monastery, until between 1380 and 1389, after the internecine wars between Peter I and his illegitimate brother Enrique de Trastámara, it was rebuilt by Archbishop Pedro Tenorio.
It did not remain in good condition for a long time, since in the sixteenth century it seems that it returned to present state of ruin, not being restored but it was used for different functions, as it consists of Polvorón in 1857. In 1873, because of its deplorable state, it went to auction for price lower than 3,500 ₧ (€21), which originated that it intervened in 1874 the Provincial commission of Monuments declaring to the Castle National Monument, being the first castle in the peninsula to receive such Denomination. Various archaeological works carried out in 1920 discovered several medieval tombs.
The building was ceded in 1945 to the youth delegation, who restored the castle for its own purposes. It is currently used as a hostel and a university residence.
