Strängnäs Cathedral is built mainly of bricks in the characteristic Scandinavian Brick Gothic style. The original church was built of wood, probably during the first decades of the 12th century, on a spot where pagan rituals used to take place and where the missionary Saint Eskil was killed during the mid 11th century. The wooden church was not rebuilt in stone and bricks until 1296, just after Strängnäs became a diocese. The cathedral was probably inaugurated by bishop Styrbjörn in 1334.
The oldest murals date from the 14th century. The Strängnäs Cathedral was enlarged in several phases during the 15th century and it was damaged by fire in 1473. Bishop Kort Rogge (1479-1501) donated two crucifixes which are still located in the cathedral. The larger one is made in Brussels around 1490. There are also many other significant medieval artefacts in the cathedral. The cathedral contains also the burials of Charles IX of Sweden and Maria of Palatinate-Simmern.
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.
