"Document Legionslagermauer” in Dachau Square, Regensburg

Located in the Dachau Square is the impressive "Document Legionslagermauer." This remarkable site can be explored through a captivating digital presentation at the information center situated in the basement of the car park. To access it, visitors can use the staircase accessible from Königs Street.

Within this underground space, a section of the fortification measuring approximately 230 feet (70 meters) in length and up to five ashlar layers high has been preserved. This represents the longest remaining straight segment of the Roman wall in existence.

As you descend the steep staircase into the basement, you'll immediately notice the variation in height between the Roman habitation layer, indicated by the wall's podium, and the current street level. This eastern section of the legionary fortress once formed part of the city walls until the early fourteenth century when it was repurposed for the convent of the Poor Clares and eventually filled in. Although the ashlars undoubtedly originate from the Roman period, modifications and repairs from later periods are discernible.

On the car park basement wall, across from the Roman wall, you'll find a regular-sized and a large monitor displaying a twelve-minute video presentation. This video provides insights into the legionary fortress wall, with a particular focus on the uncovering and details of this specific section. Additionally, there is another video explaining the construction history of the southeast corner of the Roman wall.
