Rustovo Monastery is located around three kilometres above the Praskvica Monastery. It is dedicated to the Assumption of the Holy Mother of God and it has been convent since 2004. The graves of monks were discovered in the monastery yard, which proves that a number of monks lived here as early as in the Middle Ages. Within the Monastery complex, there is a little chapel dedicated to St Benedict of Nursia, as well as a more recent church dedicated to the Holy Royal Martyrs, the Romanovs.
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.
