Castra of Stuttgart-Bad Cannstatt, Roman military fort in Bad Cannstatt, Stuttgart, Germany
The Castra of Stuttgart-Bad Cannstatt is a Roman military fort from the 1st century, built on the bank of the Neckar River in what is now the Bad Cannstatt district of Stuttgart. It followed the standard rectangular layout of Roman forts, with outer walls, ditches, and stone buildings arranged in an organized grid inside.
The fort was built around 90 AD when Rome was pushing its frontier deeper into Germanic territory and needed to control the Neckar crossing. It was later enlarged and remained in use until the Romans withdrew from the region in the 3rd century.
Objects found at the site show that goods and people arrived here from many parts of the Roman Empire, leaving traces in tools, pottery, and personal items. Looking at these finds gives a real sense of what daily life was like for the soldiers and civilians who lived at this frontier.
The site is open as an archaeological park, where information panels on the ground explain the layout and history, and the exposed foundations can be walked around. A visit works best in good daylight since most of what survives is outdoors and benefits from clear visibility.
Just next to the fort, eleven mineral springs were used by the Romans and still flow today, making this one of the few ancient military sites directly tied to a working thermal spring area. The springs fed both the military and the civilian settlement that grew up around the fort.
