The Palais Strousberg was a large city mansion built in Berlin, Germany for the railway magnate Bethel Henry Strousberg. It was designed by the architect August Orth and built between 1867–68 at No.70 Wilhelmstraße. The grandiose splendour of its accommodation and novel integration of the latest building technologies into the fabric of the building, ensured that Berliners would still find the Palais impressive decades after its construction, becoming the model of refined luxury in Berlin architecture.
