On the slope of the hill between the Forum Square and the upper circular street, lies the monastic complex dedicated to St. Francis of Assisi, built in the 14th century at the site of a previous cultic edifice. The Franciscan community was first recorded in Pula in the 13th century. The church was built in 1314 in the late Romanesque style with Gothic ornaments, as a firm and simple building of the preaching Franciscan order. The finely cut stone blocks used for building the walls speak of the skilful masters who took part in the construction.
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.
