Alb Limes

The Alb Limes (German: Alblimes) is a Roman frontier fortification or limes of the late 1st century AD in the Swabian Jura, also known as the Swabian Alb. The Alb Limes runs for just under 135 kilometres from Rottweil (Latin: Arae Flaviae) in the southwest to Heidenheim an der Brenz (Latin: Aquileia) in the northeast.
