Main Limes

The Main Limes, also called the Nasser Limes, was built around 90 AD and, as part of the Upper Germanic-Rhaetian Limes, formed the frontier of the Roman Empire in the area between the present day villages of Großkrotzenburg and Bürgstadt [1]. In this section the limes adjoined the River Main (Moenus), which forms a natural boundary for about 50 kilometres here, so "Main" refers to the river [1]. However, of the many watchtowers that probably stood along the Main, to date only one south of Obernburg am Main has been identified [1]. North of the Main the limes initially runs through the marshy terrain of the Schifflache and Bulau before linking up with the Wetterau Limes [1]. At the crossing of the Main at Großkrotzenburg a Roman bridge has been identified from post sockets [1]. In the south it extended in its early period to Obernburg or Wörth [1].
