The hermitage of San Román de Moroso is a beautiful and genuine example of the Mozarabic art or Repopulation art in the region of Cantabria. This small hermitage erects in a remote gulley of the hills of Bostronizo. It scarcely reaches 12 metres long and six metres wide. Its dating is possibly from the 10th century, although there is not any document to confirm it. However, the first document that proves the existence of the monastery of Moroso is of 1119, the year in which the queen Doña Urraca donates the property to the monastery of St. Domingo de Silos.
It is a construction of regular proportions and perfect adaptation to its volumes. The building, gabled, is made of ashlar stone with pieces well squared in corners and jambs of the spans, put together with mortar. The apse is quadrangular and the gable finishes off a bell gable of later construction. The eaves stands up with foiled modillions decorated with swastikas, sun disks and four and six petal flowers. The origin of the vegetal motifs as well as the geometrical ones were profane representations though christianized later by the Visigoths and finally adopted by the Mozarabics. The inside is formed by a single rectangular and remarkably high nave with wooden frame.
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.
