The present Odense Cathedral dates primarily from the 13th century, but it was built on the foundations of an earlier travertine church that was built in 1095. During the civil war between Eric IV and his brother, Abel, Odense and the cathedral were burned down in 1247. The present church was constructed in several phases to replace the aging and inadequate stone church in about 1300 by Bishop Gisico (1287–1300). The new cathedral was built in Gothic style with its typical pointed arches and high vaulted ceilings. The building material of choice for the time was over-sized red brick which was cheaper and easier to work with than the porous stone available. Portions of the stone cathedral were taken down and the new building expanded around the old. In all it took approximately two hundred years to complete the cathedral, which was finally dedicated on 30 April 1499.
The church is dedicated to St. Knud, aka King Canute IV. In 1086, Canute was murdered by Jutish peasants angry at his heavy taxation. He was slain along with his brother Benedict and 17 members of his entourage while kneeling at the altar of the nearby St. Alban's Church, where they had taken refuge. The remains of the church have been excavated in the city park. When the first church of St. Canute was completed, a three day fast was proclaimed for the entire kingdom and the remains of Canute and Benedict were moved to the cathedral. It was believed that if the king was truly a saint that the shroud should be set on fire and the body would not be harmed. The shroud of Saint Canute was set alight, but the fire indeed left no mark upon the body of the king.
Odense Cathedral is the purest example of Gothic architecture in Denmark. Inside, it boasts a splendid 16th-century altarpiece by Claus Berg. Other highlights of the cathedral are definitely the reliquaries containing the skeletons of King St. Knud and his brother Benedikt. The skeleton believed to be that of Knud has undergone forensic investigation and it bears evidence of a club swing from behind - supporting the tradition that Canute was murdered while kneeling at prayer.
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.
