Church of Santa Eulalia de la Lloraza is a Romanesque-style church in the municipality of Villaviciosa. The origins of the church are not clear, although the origin of the church may be the endowment by a leper who traveled the Camino de Santiago route which passed through the area. The church may have been funded initially by an offering of Queen Berengaria of Castile, wife of King Alfonso IX of León.
The present church dates from the thirteenth century, having undergone numerous renovations after it was damaged by arson in the Spanish Civil War. The church was restored in 1950 by Luis Menéndez Pidal y Alvarez.
The church has a nave with a squared apse. The ensemble seen today has elements of several epochs, as it has since undergone repairs and refurbishments.
The two entrances of the building are from the early days of construction, featuring richly Romanesque decorations.
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.
