The Celtic camp of La Bure, located in Lorraine, France, is one of the many fortified hilltop sites bordering the Upper Meurthe Valley. The plateau, now covered by forest, is shared between the communes of Saint-Dié-des-Vosges and Hurbache, at the western edge of the Ormont massif.
This hilltop settlement, of the 'spur' type, fortified to the east, is situated on a sandstone promontory overlooking the Meurthe Valley by more than 200 meters. It was intensely occupied during the 2nd and 1st centuries BC, particularly at the end of the second Iron Age and the period of Gallic independence, as well as throughout most of the Roman period, from the 2nd to the 4th century AD. The site's occupation dates back at least to the Late Neolithic, as evidenced by numerous stone artifacts made from flint, such as chisels, scrapers, blades, arrowheads, and polished axes crafted from other materials.
A few shards of green-glazed pottery are believed to date from the Middle Ages. This archaeological collection is stored and partially displayed in the archaeological section of the Pierre-Noël Museum in Saint-Dié-des-Vosges, where a model of the entire site can also be seen.
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.
