The Cathedral of Ávila has Romanesque and Gothic architectural traditions. It was planned as a cathedral-fortress, its apse being one of the turrets of the city walls. It is surrounded by a number of houses or palaces.
It is not known exactly when the construction of the Cathedral began, there being two theories. One states that Alvar García started its construction in 1091 inside the remains of the Church of the Saviour, which was in ruins as a result of successive Muslim attacks, and that Alfonso VI of Castile raised the money necessary to build it. Other historians believe the Cathedral to be the work of the maestro Fruchel in the 12th century coinciding with the repopulation of Castille led by Raymond of Burgundy.
Of the 13th century are the first stages of the towers and aisles and of the 14th century the second stage of the towers, the cloister, the vaults and the flying buttresses. Already in the 15th century the cathedral was complete and in 1475 Juan Guas built the mechanical clock.
The Cathedral of Ávila is considered by its age (12th century), along with the Cathedral of Cuenca, as the first two Gothic cathedrals in Spain. It shows French influences and great resemblances to the Abbey Church of St Denis, the first European Gothic church.
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.
