Santa María da Armenteira Monastery belongs to the Cistercian order and was founded by the knight Ero de Armenteira in 1168. It has a square cloister, a kitchen, and a tower, all in the 18th-century Baroque style. The monastery was abandoned after the sale of church lands in 1835. The church has a floor plan in the shape of a Latin cross, three naves and three semicircular apses. The central nave is crowned with a pointed barrel vault, and the side naves with groin vaults. The transept has a vault raised on Mudéjar-style pedentives. On the façade, the 12th-century rose window is of particular interest. The whole complex has today been rebuilt thanks to the Association of Friends of the Monastery of Armenteira.
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.
