Even earlier, the army had resettled members of a Germanic tribal group allied with Rome, the Ubii, in Bonn.

The Latin name for that settlement, "Bonna", may stem from the original population of this and many other settlements in the area, the Eburoni.

The Eburoni were members of a large tribal coalition effectively wiped out during the final phase of Caesar's War in Gaul.

After several decades, the army gave up the small camp linked to the Ubii-settlement.

In about 12 BC, the Roman army appears to have stationed a small unit in what is presently the historical centre of the city.

They were used by Frankish kings until they fell into disuse.

Eventually, much of the building materials seem to have been re-used in the construction of Bonn's 13th-century city wall.

The geographical centre of Bonn is the Bundeskanzlerplatz (Chancellor Square) in Bonn-Gronau.

The German state of North Rhine-Westphalia is divided into five governmental districts (German: ).
