The theatre building, designed by the Berlin architect Schnitger and opened in 1890, is now a listed historical monument. The new foyer, constructed of glass and steel, is located on the west side, parallel to the exterior wall of the original building. It offers a view of the neoclassical facade and incorporates its rhythm in both the arrangement of the columns and the mullioned structure of its facade. Tree-like, green-painted columns create a visual link to the adjacent park. Their design evolved from the formal concept of an artificial avenue within the pavilion, serving as a connection to the exterior space.
