Castra of Würzberg, Roman fort archaeological site in Würzberg, Michelstadt, Germany

The Castra of Würzberg is a Roman numerus fort on a clearing at about 525 metres on the ridge south of Würzberg. Its irregular four-sided rampart measured 72.03 m at the front, 74.10 m at the rear and roughly 81 m on the sides, enclosing some 6,000 square metres. The wall contours remain visible in the open ground, and the conserved foundations of the fort bath, about 60 m south of the right gate, show parts of the standing masonry.

The fortification was built in the first century and served as part of the Neckar-Odenwald-Limes, which marked the northern boundary of the Roman Empire. This frontier post played a key role in controlling the empire's territory against incursions from outside groups.

The fort's name lives on in two older forms: a Wllineburch recorded in an 819 description of the Mark Michelstadt and a destructa Vullonoburg in a 1012 Lorscher Wildbann charter, though their identification with the site is uncertain. The garrison itself, a numerus of about 160 auxiliaries, is unnamed in the sources.

You can reach the archaeological site by following marked hiking trails that connect several Roman fortifications along the Limes route. Wear sturdy shoes and prepare for uneven ground, as walking across the site on foot gives you a better sense of its scale and layout.

The fort kept its original rectangular shape with four entrance gates, showing how standardized Roman military designs were across the empire. This carefully planned layout allowed soldiers to move quickly and defend the grounds in an organized way.
