Founded by the Duke of Calabria, the San Miguel de los Reyes Monastery is one of the best examples of the Valencian Renaissance, and can be considered the prototype for El Escorial, as it was designed to be a Royal Pantheon, a Hieronymite monastery, a college and a church. However, various mishaps prevented the project from being completed in its entirety. The two architects who designed it in 1546 were Alonso de Covarrubias and Juan de Vidaña. Following the death of the Duke, the construction was interrupted for more than twenty years. Other criteria were then considered, but the first group of buildings fully assumes the Renaissance style.
Recently restored and inaugurated (in 1999) it serves as the Valencian Library.
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.
