Designed as part museum, part science center, the Forum Deutsche Sprache (German Language Forum) in Mannheim is a unique building where science and society engage in dialogue. The Leibniz-Institut für Deutsche Sprache (Leibniz Institute for the German Language) will use it as an exhibition space and interactive research facility. It creates a public meeting place where interactive presentations, discussions, and ongoing research allow visitors to experience the nature of language, its omnipresence and diversity.
The Forum Deutsche Sprache will be situated at Alter Messplatz in the Neckarstadt district in the northern part of Mannheim. The new build aligns with the urban perimeter of the square and extends it towards the Neckar River, whose riverside will be undergoing a redesign at the same time. Three stories rise from the ground f loor, which is almost fully glazed. They project from the building base into the space above the square to invite visitors to explore the interiors. This design creates an open forum, a floating space between inside and outside – lobby and square – that provides a place to meet for all visitors, employees, and people from the neigh borhood. This is where a glazed space opening views of the Neckar River provides options for special exhibitions, readings, and science slams. The setting also includes a publicly accessible picnic area extending towards Alter Messplatz.
The exhibition tour starts on the third floor after an elevator ride and winds its way down to the ground floor. In a virtual presentation designed by Atelier Brückner, visitors experience linguistic diversity, the continuous evolution of the German language in contact with other languages, language technology, and social discourse in different language worlds. They can contribute to linguistic research themselves by interacting with the exhibits and giving spoken or written “language donations.” Office spaces for researchers are integrated directly into the two lower exhibition levels. A top-floor roof terrace offers a panoramic view of the Neckar River and city skyline. It is accessible for employees and museum visitors alike.
The robust concrete structure remains visible across all floors to determine the building’s architectural expression. Beams and columns divide the levels into smaller zones, each of which houses a different language world as part of the exhibition. Alluding to the multifaceted nature of language, a multilayered façade envelops the new build. The interior structural framework is designed as a concrete skeleton enclosed by an alternating façade composed of closed timber frame elements and a post-and-beam structure, which, in turn, is covered by adjustable wooden louvers. A fixed protective ETFE film layer placed in front of these wooden elements enhances the striking character of the building.
The Forum Deutsche Sprache endowed by Klaus Tschira Stiftung adds a new cultural site to Neckarstadt that provides a space for intergene rational dialogue, inclusion, and exchange in this urban district. Like language as such, the building facilitates connection and communication.
