The Monastery of Fitero is a Cistercian monastery located at Fitero, on the banks of the Alhama river.
It was founded, on a different site, in 1141 as part of the Cistercian expansion into Spain from the center at Escaladieu Abbey, and moved to Fitero in 1152. Durand was its first abbot, followed by St. Raymond of Fitero, who later founded the Order of Calatrava.
The floor plan of the church is similar to that in the monasteries of Clairvaux and Pontigny, a Latin cross plan with three naves, the ambulatory sanctuary with five side chapels.
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.
