The Stapferhaus was founded in 1960 as a place of encounter and intellectual debate. It is known for its exhibitions on socio-political issues.
Since 2018, they are on display in a new building, designed by Pool Architekten, right next to the Lenzburg train station. The building is designed to be constantly transformed: stairs and walls can be shifted, floors opened, the façade and forecourt can be altered.
A metal spiral staircase connects the different levels of the museum.
