Main Limes

The Main Limes (German: Mainlimes), 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.
