Eskelhem Church was preceded by a wooden church, of which nothing remains. Circa 1200 it was replaced by a stone church. The walls of the nave of the present church are all that remains of this edifice. The church was successively enlarged and rebuilt until it received its present form in the middle of the 14th century.
Internally, the church is decorated with different sets of frescos, dating from the end of the 13th century and the 15th, the latter by the Master of the Passion of Christ. Among the church furnishings, the baptismal font from the 12th century, probably made by Master Byzantios, and the triumphal cross, made around 1250 both deserve mention.
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.
