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.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
