The Timpone della Motta is a hill two kilometers to the southwest of Francavilla Marittima. It is an archaeological site which was inhabited since the Middle Bronze Age. In the Iron Age the hill was the site of an Oenotrian settlement. Over time the settlement was transformed into an important sanctuary, which was notable as the site of the first known ancient Greek temples on the Italian Peninsula. The Oenotrians were influenced by the culture of the Greek colonists from nearby Sybaris, who eventually took over the site in the second half of the seventh century. The hill was abandoned when the Bruttians conquered the region in the fourth century BC.
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.
