Burgus Untersaal

Burgus Untersaal is an archaeological site containing remains of a Roman fortification that forms a square shape measuring about 17 meters on each side and sits high above the Danube. The location includes preserved stonework and soil layers that show the internal layout of the structure.

The fortification was constructed between 370 and 372 CE during the reign of Emperor Valentinian. It served as part of a larger defensive system guarding against threats from across the river.

The site takes its name from a nearby settlement and still shows visible traces of its original purpose as a watchtower along a vital river route. Visitors can see the foundation layout and understand how Romans controlled this stretch of the Danube.

The site is mostly open ground and requires walking along field paths to explore it fully. Visitors should bring appropriate footwear and weather protection, as the area is exposed and can be windy.

Excavations in the early 1900s and following decades revealed that Romans had reused existing stones from older structures when building here. Discoveries such as pottery and tools can be seen today in the Archaeological Museum of Kelheim.
