This Roman Fort is a partially reconstructed timber fort situated in the West Midlands and includes a Gyrus, a feature not found anywhere else in the entire Roman Empire. The Gyrus is a large circular structure on the east side of the fort. The ring is 34.06m in diameter with a funnelled entrance and double gate, probably indicating that the structure was used for livestock of some sort.

The Fort has four gateways: Porta Praetoria, the Porta Decumana, the Porta Principalis sinistra and the Porta Principalis Dextra. The gates vary in height to between 9.15m to 10.65m high.

Other buildings or places of notice around the fort include: the Fabricae (the work shop) the Horreum (the granary) Principia (headquarters and religious centre) the barracks and the Praetorium (the commanders house). The Praetorium was unusually large for a fort of Lunt's size, so this probably meant that the commander was someone of importance.

One distinct difference with this Fort and other Roman forts is that this one is not in the perfect playing card shape that most Roman forts were. Instead it has a bulge on its side, caused by the Gyrus. Also on the northern side of the fort instead of a wall there is a steep bank. The Fort is unique as it makes use of the natural shape of the landscape rather than the traditional Roman method of ignoring the local area shape and building in complete straight lines.
