In 2007, the Building Committee approved a redesign of Karmeliterplatz and the area surrounding the St. Christopher Memorial. Due to a lack of funding, the project could not be implemented initially. In 2011, thanks to a private donation, the memorial and the area surrounding the church ruins were upgraded; however, Karmeliterplatz and the adjacent paths remained unchanged. In 2015, the project became part of the Integrated Downtown Development Concept (IEK) and was to be funded through the “Active City Centers” program. After funding ended in 2022, planning continued due to the significance of Karmeliterplatz and Brückenplatz as key connecting points and hubs for pedestrian and bicycle traffic. In early 2026, it was decided to reapply for the urban development funding program. The goal is to revitalize Karmeliterplatz and Brückenplatz, improve the quality of the public space and connectivity to the banks of the Rhine, and contribute to climate protection, accessibility, and the removal of impervious surfaces.

To gather ideas, a framework plan is currently being developed with citizen participation.

The following steps are being taken:

1. Development of the urban planning framework (framework plan);
2. Coordination and involvement of the relevant departments;
3. Public participation;
4. Political approval of the framework plan;
5. Preparation and subsequent implementation of a procurement process.

Mainz Old Town

A draft master plan for the future development of the area is currently being prepared. It will be presented to the citizens of Mainz at a public participation event on November 17, 2026. The City Council will then discuss and decide on the master plan. Once the decision is made, a bidding process will begin.

The expected costs are currently being determined as part of the planning process and the eligibility assessment. If the project is included in a federal-state urban development funding program, up to 90% of the costs may be covered by grants.

A framework plan is currently being developed with the participation of Mainz residents and city officials. This plan serves as preparation for a bidding process for the Karmeliterplatz and Brückenplatz areas, including the connection to Rheinstraße.
