Pre-Christian basilica with a regular layout, the central nave paved with a magnificent mosaic which can still be seen. It dates from the 6th century A.D., when the Byzantine army of Justinian (the Eastern Roman Emperor who aspired to rebuild the Western Roman Empire) had conquered the Balearic Islands.
It faces from east to west, and on the northern side retains a small hemispherical baptismal font built in stone and mortar, with a waterproof lining.
There are three separate sections: The rectangular apse with the base of an altar, surrounded by bunches of grapes, the central motif being a classical wine bowl and two peacocks. The grapes represent life, while the peacocks facing one another represent the resurrection. Between the nave and the head, two lions face a palm tree. They have been interpreted as a reference to Jewish tradition, which was particularly important at that time in Maó. The lions represent the power of death, while the palm is the tree of life. The nave for the congregation reveals geometric figures and depictions of birds, in a clearreference to Paradise.
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.
