Salvaterra de Miño has always carried out an important military function because of its strategic location next to the Miño River.
There is hardly anything left of the original 12th century walls that used to protect the castle. The fortress, however, built in the 17th century, still stands, and was refurbished in 2008. As well as many sentry boxes on the walls, other buildings were built such as the Baroque chapel (17th century) of La Virgen da Oliveira and the Casa del Conde house (17th century), with the Doña Urraca caves and double room with a spiral staircase can be found.Inside the fortress, as well as remains of streets, houses and gravestones, we can find the palace or manor house of Doña Urraca, named after the room of Queen Urraca I (1109-1126) during a war with the Countess Teresa of Portugal.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí.

Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
