In 1897 Burtscheid was incorporated into the city of Aachen, but the administrative seat stayed there, even though the capital was no longer part of the district.

At that point in time, the policy that no independent large city in North Rhine-Westphalia should be the seat of its district was not yet in effect.

In the case of Aachen, however, no further municipal reform was carried out and the separation of city and district remained.

Its regular meetings consisted of 60 representatives of the association members with voting rights, and focused on expanding cooperation between the members, road traffic management, school administration, and economic development.

[4] Geographically the district covers a part of the Eifel mountains in the south, but also the lowlands of the Lower Rhine Bay.
