The Monastery of San Lorenzo de Carboeiro is one of the most outstanding architectural works of the late Romanesque, the transition to the Gothic, in Galicia.
Its gestation was founded in the year 939 AD. When the construction was completed, the priest Felix was chosen as the first abbot of the community.
Its moments of greatest splendor were between 11th and 13th centuries. Abbot Fernando, from 1162 to 1192, expanded the church. At this stage the monastery belonged to the 'Cluny' order, and for a long period has a rich estate.
During the 15th century lawsuits, neglect and mismanagement, lead to the community’s ruin, and in 1500 by order of Ferdinand and Isabella, it is relegated to the status of priory, a farm for San Martiño Pinario in Santiago, prolonging its decline, including a prison built for monks in 1794 and until 1836, coinciding with tits confiscation by Mendizabal, and its total abandonment.
The church and some other buildings are still in good condition, after the works of restoration and recovery made during the second half of the twentieth century.
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.
