The Colonne di San Basilio (Columns of St Basil) are an ancient Greek structure, which take their name from the mountain of San Basilio where they are located, in the territory of Lentini.
The summit of the mountain shows trances of ancient settlement from the prehistoric period, with clear traces of the postholes of a hut, probably belonging to the Casteluccio culture.
A little way away is the imposing structure itself, carved in the limestone rock and measuring 18 x 16 metres, with 32 columns designed to support rock slabs. Part of the structure has collapsed, but many of the columns remain standing.
The structure was later reused by the Byzantines, who converted it into a church. Some traces of religious frescoes are even visible on some of the columns, but they are not legible.
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.
