(Augsburg). Cannstatt was a part of the Roman imperial province Germania Superior. As with many military installations, a settlement sprang up nearby and remained there even after the limes moved further east. When they did, the town was left in the capable hands of a local brickworks that produced sophisticated architectural ceramics and pottery. When the Romans were driven back past the Rhine and Danube rivers in the third century by the Alamanni, the settlement temporarily vanished from history until the seventh century. Middle Ages In 700, Duke Gotfrid mentions a "Chan Stada" in a document regarding property. Archaeological evidence shows that later Merovingian era Frankish farmers continued to till the same land the Romans did. Cannstatt is mentioned in the Abbey of St. Gall's archives as "Canstat ad Neccarum" () in 708. The etymology of the name "Cannstatt" is not clear, but as the site is mentioned as condistat in the Annals of Metz (9th century), it is mostly derived from the Latin word condita ("foundation"), suggesting that the name of the Roman settlement might have had the prefix "Condi-." Alternatively, Sommer (1992) suggested that the Roman site corresponds to the Civitas Aurelia G attested to in an inscription found near Öhringen. There have also been attempts at a derivation from a Gaulish *kondâti- "confluence". In AD 950, Duke Liudolf of Swabia, son of the current Holy Roman Emperor Otto I, decided to establish a stud farm for his cavalry during the Hungarian invasions of Europe on a widened area of the Nesenbach river valley south of the old Roman castrum. The land and title of Duke of Swabia remained in Liudolf's hands until his rebellion was quashed by his father four years later. In 1089, Bruno of Calw built the precursor building to the Old Castle. Stuttgart's viticulture, first documented in the Holy Roman Empire in the year AD 1108, kept people in the area of that stud farm for some time, but the area was still largely overshadowed by nearby Cannstatt because of its role as a local crossroad for many major European trade routes. Nevertheless, the existence of a settlement here (despite the terrain being more suited for that original stud farm) during the High Middle Ages is provided by a gift registry from Hirsau Abbey dated to around 1160 that mentions a "Hugo de Stuokarten". A settlement at this locale was again mentioned in 1229,
