It is the last building of the electoral period, a house of game and dancing for the court society, a building which was erected on the orders of Elector Max Franz in a noble Classicistic style, in order to support his health resort Godesberg. The architects were Michael Leydel, father and son. They created a central tract with three axes, which is crowned by an attic carrying six figures. In its interior, in the so-called “Beethoven hall”, the decoration of this extremely elegant period is still as it used to be.
