Ayios Philon Church was built in the 10th century, on top of a much earlier, possibly 5th Century, basilica, and is virtually all that remains of the ancient Phoenician port of Karpasia. Founded by King Pygmalion of Cyprus, it was a flourishing trading port, half way between Salamis and Anatolia. It was, however, abandoned in 802, after Arab raiders burnt and sacked it and its inhabitants moved inland, founding Dipkarpaz.
Traces of the old harbour wall can still be seen off shore, but the majority of the village is now under sand dunes to the west of the church. The church is named after St. Philo, who converted the people of the area to Christianity, and had been ordained by St Epiphanios in the 4th Century. (St Epiphanios' Basilica is to be seen at Salamis) It is a typically domed Byzantine church, with a three-part apse and a courtyard surrounded by columns. There is a cistern and baptising room, as well as numerous mosaics all around from the earlier structure.
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.
