The House of Foundations presents a permanent exhibition on the tasks and work of the foundation that supports the Krämerbrücke cultural monument. Visitors also have the opportunity to view the cellar, ground floor and upper floor of the restored bridge house dating back to 1578, which includes a timber-framed room. Questions about the construction history and planned restoration measures for the arched bridge and its bridge houses can be answered here. The history is illustrated not least by a 1:100 model of the entire Krämerbrücke.
