Markovi Kuli or Marko's Towers are situated to the northwest of Prilep, just above the village of Varoš. The towers, named after Serbian medieval Prince Marko Mrnjavčević, are located on a 120–180 m high hill, surrounded by steep slopes covered with minute granite stones. The upper part of the former settlement can be reached from its north and south side.
During the four-decade archaeological research, remnants indicating the existence of an early antique settlement — Keramija, were found. In the Roman period, this small village expanded into the southwest, a fact suggested by the several marble ornaments of an early Christian basilica.
The rampart on this terrain dates from the 13th and 14th centuries and is in good condition. The walls are about one meter thick and were built of limestone mortar and rest upon the large limestone rocks.
Internal walls separated the acropolis into smaller areas. The palace of Serbian King Vukašin and his son Marko was also situated here. Its north gate has a compound foundation - an evidence for of numerous reconstructions of the space. According to some historical findings, until the second part of the 14th century and even later, this fortress was defended by only 40 soldiers.
The settlement was situated south of the acropolis on a surface of some 3,6 hectares. On its north side, there is a double gate, as well as a large guardhouse between the entrances. On the south wall there are three well-preserved towers.
The lowest zone of the rampart consists of a row of short walls drawn in a broken line. In the west side, there are graves inserted into the rock. In the 14th century, this part served as a temporary refuge of the local population from Turkish raids.
After the death of King Marko in 1395, this settlement was taken by Ottoman forces. At this time the inhabitants of the former settlement migrated to a new settlement at the foot of Marko's towers. It was separated into several quarters and each had its own church. This new settlement from the 14th century was given the name Varoš which is still in use today.
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.
