The Fortaleza del Castro is a hilltop fortress in Vigo built in 1665 during the Portuguese Restoration War in order to protect the city from the continuous raids by the British Royal Navy, allies of Portugal.
Built on the hill of the same name, the defensive system of the city consisted of the fortresses of Castro and San Sebastián and the now disappeared city wall. The city wall had an irregular shape due to the orography of the city, it was constructed by the Engineer Colonel Fernando de Gourannanbergue and maestre de campo Diego Arias Taboada to link the two fortresses. Despite this effort to provide security to the city, documents from that time say that this defensive system was ineffective as it could not impede landings further along the coast.
After several attempts to improve the defenses of the city, Vigo was looted again by British navy on the 23-24 October 1702 during Battle of Vigo Bay at the War of the Spanish Succession.
In 1809, the fortress was occupied by the French army during Peninsular War; on 28 March that year the fortress was reconquered following an uprising by people of Vigo, because of the city was given the honorific title of 'the faithful, loyal and courageous city of Vigo' the following year.
Nowadays the fortress is one of the preferred sites for people to take a walk in Vigo, because his beautiful gardens, open spaces, fonts and also the privileged views.
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.
