Lin is situated on a small peninsula on Lake Ohrid. The Lin area has been inhabited since at least the Iron Age. Archaeological findings from the hilltop above the present-day village include foundation walls and mosaics of an early Christian Byzantine church, dating from the 6th century. The church is included within the possible UNESCO site of the Natural and Cultural Heritage of the Ohrid Region.
The ruins of the paleo-christian church of Lin together with its floor mosaics from the 4th-5th century reveal the presence of Christianity.
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.
