Trento Cathedral (Duomo di Trento) was built in 1212 over a pre-existing 6th-century church devoted to Saint Vigilius, patron saint of the city. Bishop Federico Wanga commissioned the architect Adamo d'Arogno to construct the new Lombard-Romanesque church. Works continued for more than a hundred years, with the Gothic style becoming increasingly evident.
The façade has a large rose window including The Wheel of Fortune. Notable also are the lions supporting the columns of the narthex on the northern side and the twisting columns in the apsidal area.
The interior has a nave and two aisles with a transept. The latter has 14th-century frescoes depicting the legend of Saint Julian and the stone statue of the Madonna degli Annegati. The apse of the right transept houses the relics of the local martyrs Sisinius, Marturius and Alexander who died around 397 AD. In the right aisle is the Crucifix Chapel (1682), with a wooden crucifix at the feet of which were promulgated the issues of the Council of Trent, whose sessions were held in the church's presbytery. Painter Ludovico Dorigny also contributed works to the cathedral.
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.
