The museum hosts an impressive collection of uniforms, photographs, documents and reservisticas associated with the garrison of Mainz. Visitors can also see a beautiful model of the former fortifications of Mainz. All exhibits are part of the private collection of Wolfgang Balzer who also acts as the curator. The "Museale Magazin der Festung und Garnison Mainz", to give it its full name, is open to all visitors by appointment (at the moment, the collection is moving house and cannot be seen). Wolfgang Balzer personally guides visitors through his exhibition, giving an interesting and entertaining introduction to the history of Mainz and its fortifications. You also have time to stroll through the museum on your own, while Wolfgang Balzer is available to answer any questions you might have. This compact museum is well worth a visit, as it provides an entertaining introduction to the military history of the city of Mainz.
