Solofra is located at the foot of the eastern slope of the Vellizzano and Faito Mountains. The first historical record of the hamlet dates back to 1015, its lord was a certain Maione. In 1417, the fief passed to Francesco Zurlo, Count of Montoro and then to the Filangieri Family who besieged the Castle with a large army. In 1528 the fortress passed to the family Orsini, to whom dynasty the fief belonged until the abolition of feudalism in 1806.The ruins of the Castle consist chiefly of two angle-towers and some crumbling curtain walls.
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.
