Traismauer-Augustiana
Auxiliary fort
The auxiliary fort, which is approximately 3.7 ha large, lies below the medieval city centre. There are several well preserved, high raising monuments, such as the fort´s east gate, a U-shaped tower on the northern curtain wall and a Late Roman fortlet still recognizable in the groundplan of the Traismauer Castle. The main street grid in the center oft he town still follows the outline of the Roman fort.
The fort is located on a slightly elevated terrain east of the River Traisen’s mouth, at the crossing of transportation routes and the navigable river. There is an earlier earth-and timber construction followed by a later fort built of stone. The civil settlement stretched along the road leading from the eastern gate and south of the fort.
