To underline the importance of this anniversary, the municipal administration, under the leadership of Deputy Mayor Hajo Böser, has planned numerous celebrations that will take place from September 26th to October 4th, 2025. A diverse program is offered. It starts with a performance by comedian Amjad, followed by a cozy breakfast buffet on Sunday, September 28th.
Festivities in detail
The anniversary festival offers something for every age group. On October 2nd, local band “Rip & Funk You” will provide musical entertainment. Especially for the younger ones, there is a children's day on October 3rd, where live theater is on the program. A seniors' day with a delicious white sausage meal will also be organized for older citizens on October 4th.

A look back at the regional reforms
The merger of Rheinhausen and Oberhausen is part of a larger municipal regional reform that took place in Germany in the 1960s and 1970s. In North Rhine-Westphalia, the reform began in 1966 and ended in 1975. During this time, numerous municipalities were reorganized in order to simplify administrative structures and increase the efficiency of public tasks. [Wikipedia, regional reform in North Rhine-Westphalia, explains that ...](https://de.wikipedia.org/wiki/Regional reform_in_Nordrhein-Westfalen). After the reform, the number of municipalities in Germany was significantly reduced, which included both voluntary and legally mandated mergers.
The motivation behind these reforms was clear: the existing structures no longer met the requirements of the time. So it was not surprising that after the reform the number of district municipalities in North Rhine-Westphalia was reduced from 2327 to 1243. This has strengthened the administrations in the new larger units and improved their ability to act [Wikipedia, Regional Reform, emphasizes that ...](https://de.m.wikipedia.org/wiki/Regional Reform).
In Oberhausen-Rheinhausen, a sign of togetherness is now being set with a look at the past and the ongoing development of the community. Participants and visitors can look forward to an exciting week of festivals that will reveal the lesser-known but impressive history of the region.
