Stadthalle Lahnstein, multi-purpose hall in Lahnstein, Rhineland-Palatinate, Germany

Stadthalle Lahnstein is a modern event venue located on Salhofplatz in the town center with multiple floors and flexible spaces for concerts, meetings, and exhibitions. The rooms can be adjusted in size and setup, equipped with modern lighting and sound systems to support different types of events.

The hall was built after the 1969 merger of Ober- and Niederlahnstein, with the foundation stone laid in June 1971 to designs by Jürgen Jüchser and Peter Ressel of Planungsring Wiesbaden. Otto Herbert Hajek created the coloured geometric relief on the main facade. In 2007 the Generaldirektion Kulturelles Erbe Rheinland-Pfalz listed the building as a Kulturdenkmal.

The hall serves as a gathering place where the community comes together for concerts, theater, and local celebrations. It plays a role in bringing people from the area together through shared entertainment and cultural experiences.

The hall is centrally located on Salhofplatz and is easy to reach on foot or by car, with parking available nearby. The spaces are well-organized and accessible, with different floors connected by stairs and elevators for easy movement between areas.

A two-metre obelisk called "Lahnstein", carved from local Lahn marble to Otto Herbert Hajek's design, divides the stairways; the same artist's "Zinnenfeld" relief in the upper foyer was removed during fire-protection works after 2005.
