Santa Catalina Monastery construction started in in 1393, in a Romanesque style when Gothic standards were already taking hold. With Mendizábal's disestablishment (1837) the Franciscans were obliged to abandon the monastery, and the building's ownership and management passed to the army until the year 2000.
The monastery has two cloisters, the best conserved of which is in Renaissance style. The church was modified in the 18th century, when it changed from a cross-shaped ground plan to a single nave covered with a barrel vault on arches. Coloured wooden retable with Baroque ornamental designs. Some of its images are in churches in Ferrol. Inside the monastery, we can see the remains of capitals, statues, tombstones. Other sculptural remains from the 16th century can presently be seen in the San Antón Archaeology Museum (A Coruña).
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.
