The necropolis in Boljuni has 274 stećak tombstones, 92 of which are decorated and 9 of which have epitaphs, making it one of the Bosnia's few large necropolises. Original motifs found in Boljuni are a lion, a woman cradling a child in her arms, stylized rosettes, fabulous lizard-like beasts, and a round dance with the leader riding a deer. Most of the monuments have been carved between 13th and early 16th centuries.
The necropolis is situated in the valley below the village houses, and distributed into two groups some 400 meters apart. In the surrounding area there are traces of Illyrians (fort and tumuli), and nearby there is the site Crikvina, probably from late antiquity, and the remains of the cemetery (early medieval).
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.
