The Maculje necropolis has 101 tombstones: 32 slabs, 52 chest-shaped, 11 gabled and six of which the shape could not be identified as they are partly buried. They are of limestone, and stand in rows. The principal shape is that of a chest on a plinth, followed by those of sarcophagus shape, with or without a plinth, and a few common slabs. One only is decorated (with an 'apple'). The necropolis also contains 16 anthropomorphic tombstones, which some authorities call cruciform tombstones, all but one decorated; the decorative motifs are a cross, a stylized cross, a Greek cross, a circle ('apple') and a crescent moon.
These anthropomorphic tombstones are a distinctive type found only in the Travnik and Zenica area, with no analogy in the areas where stećak tombstones are found.
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.
