It is located in the municipal territory of the Lower Franconian town of Marktbreit on the left bank of the River Main, in the district of Kitzingen inside the German state of Bavaria.

[1] The historic monument is located at a strategic site northeast of the actual town on the hill of Kapellenberg, a terrain spur in the acute angle between the Main (Moenus) and the Breitbach stream.

An important architectonic feature is a praetorium (commandant's residence) oriented axially and joined to the huge principia (staff building).

Along with the irregular ground plan and the design of the gate areas, this detail enables it to be dated to the time of Augustus.

The camp at Marktbreit fits into this scenario, perhaps not so much as a transit fortification with a small core staff to protect the deployment and supplies during the campaign but, in view of its size and the representative buildings, as a planned centre for large-scale conquest.

Some academics pinpoint that Marktbreit could have been the possible capital of the Germania Antiqua (a province of the Roman empire that Augustus wanted to create, before the defeat at the Teutoburg forest battle).

Furthermore, there is an archaeological hiking trail with eight information boards from the car park on the Main to the Kapellenberg, which gives an idea of the vast scale of Marktbreit's military camp.
