Innsbruck Cathedral was built between 1717 and 1724 on the site of a 12th-century Romanesque church. The interior is enclosed by three domed vaults spanning the nave, and a dome with lantern above the chancel. With its lavish Baroque interior, executed in part by the Asam brothers, St. James is considered among the most important Baroque buildings in the Tyrol.
Innsbruck Cathedral is notable for two important treasures. The painting Maria Hilf (Mary of Succor) by Lucas Cranach the Elder from c. 1530 is displayed above the main altar. It is considered among the most venerated Marian images in Christendom. The cathedral also contains in the north aisle the canopied tomb of Archduke Maximilian III of Austria, Grand Master of the Teutonic Knights, dating from 1620. The cathedral was heavily damaged during World War II, but was fully restored within a few years.
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.
