The settlement was founded around 90 AD and no pre-existing military installation is known. The town was originally the administrative centre of an imperial domain but, at an unknown point in the 2nd century, the civitas was formed with Sumelocenna- Rottenburg as capital and urban development continued into the 3rd century.
The few known stretches do not allow for full reconstruction of the road network, but the city wall, which was built in the early 3rd century enclosed an area of 28ha and was equipped with towers and an outer ditch.

A series of pillar foundations, up to 1.5m thick, has been found north of the
cathedral and belongs to a public building at least 50m in length. No associated
buildings are known.

Inside the city wall, three public baths could be identified. The partially excavated bath I contained brick stamps of Legio VIII Augusta and might have belonged to a large complex, with a series of rooms, which continues to the south-west. The smaller bath II (18 x 11m) was enclosed on three sides by walls, but only a hypocausted apse is known from bath III.

Near bath III, and within a residential building block, a large (32x 5.3m)
public latrine has been excavated. The timber seating (which is not preserved)
offered room for up to 35 people and was arranged in a U-shape over a drain.
In front of the seats freshwater in a small gully was provided for cleaning
purposes.

The temple complex in the western part of the town, was c. 50m wide and at
least 60m long. Amongst the seven buildings within the enclosure were two Gallo-Roman
temples (Length 17.5m) and two chapels (Length 5.5m). The temple complex was
built in the 2nd century but it is not known, which deities were venerated here.

Parts of two residential blocks have been excavated in the vicinity of the
latrine. To its north and separated by a road, two 10m wide and c 25m long strip
building, were found whose rooms opened off a central passage. To the south
of the latrine, a structure with four rooms was found, which was probably fitted
in later, into a gap between houses. Next to it was a (c. 50 x 24m) peristyle
house with several rooms, which is only partially excavated. Its courtyard contained
a cruciform water basin. There were sumptuous, hypocausted room flanking the
peristyle and the size of the house can be calculated as c. 1200sqm.
To the north of the structures just described, a further luxurious town house with peristyle was found behind a portico flanking the road and with heated rooms at the rear. The stone buildings were preceded by a timber phase, and similar timber phases can be identified in other parts of the settlement, where they persisted up to the mid 2nd century. | |

A pottery kiln has been found to the north-east of the city wall.
Several aqueducts supplied drinking water to the town, the longest of which came from the Rommelstal, 7.16km to the west. This is the longest aqueduct on the right bank of the Rhine and was built of limestone blocks (width 0.8m).

The public latrine has been consolidated and is now part of the Römisches Stadtmuseum
Rottenburg, where other finds from the Roman settlement are displayed.
