Gloslunde Church was built in the 13th century. Built of red brick but now whitewashed, the church consists of a Romanesque chancel and nave and a Gothic porch and sacristy. A 14th-century timber bell tower stands close to the church's northwest corner. There are two small Romanesque windows on the chancel gable, now both bricked up. The east gable is also decorated with a round-arch frieze. The original flat wooden ceiling was replaced in the Gothic period with a star-shaped vault in the chancel and two cross-vaults in the nave.
In a Neo-Gothic frame, the altarpiece contains a painting of Christ in the Garden of Gethsemane by Frederik Christian Lund in 1872. An earlier catechism altarpiece from 1581 in the Renaissance style can be seen in the porch with text from Martin Luther's catechism in its six panels. The pulpit (c. 1590), also in the Renaissance style, presents the paintings of the four Evangelists set in rural scenes with hills and hedges.
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.
