Højby Church dates back to the beginning of the 12th century and it is constructed in granite. Several modifications have taken place since the original construction including a porch in the 13th century, Gothic cross-vaulting in the nave and chancel in the 14th century, a tower around the year 1400 as well as a vestry, a chapel and a new entrance porch towards the end of the Middle Ages.
The church is recognised for its fine wall paintings which are considered to be among the best in the country from the late Gothic period. They were probably created at the beginning of the 15th century, shortly after the cross vaults were added. They were discovered in 1901 and have been restored on several occasions. During the last restoration in 2007, the painting of Erasmus' martyrdom was revealed for the first time.
The paintings in the chancel tell the story of the Day of Judgment with images of Christ, a basoon-playing archangel and St Michael. The lost souls are shown going to hell with the devil standing in its flames. There is also a painting of St George and the dragon including the Syrian princess he saved from the dragon.
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.
