The oldest parts of Västerås Cathedral date from the 13th century. It was originally built as a triple-aisled basilica in the 1230s and inaugurated in 1271. The cathedral was rebuilt and enlarged during the next two centuries. The tower was erected around 1420. The steeple was added in 1691 and it was designed by Nicodemus Tessin the Younger.
The most famous person buried to the Västerås Cathedral is King Erik XIV, the son of Gustav Vasa. The highlights of the interior are three beautiful triptychs, although there is much other fine interior furniture, including the pulpit.
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.
