The Roman estate of Büßlingen is a restored and reconstructed villa rustica ( Roman estate) from the first century AD, which existed until at least the third century.
The complex comprises nine excavated buildings on an area of 5.4 hectares. It is located south-southeast of Büßlingen, a district of Tengen in the Baden-Württemberg district of Konstanz in Germany. After the Villa rustica von Meßkirch , it is the largest known courtyard complex of its kind in southern Germany and also the only one whose buildings, determined by aerial archeology, have been completely excavated. Today it is an open-air museum.
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.
