Traces of settlement at the prehistoric Kakushöhle between Eiserfey and Weyer date back to 80,000 BC.                                                                  Hunter-gatherer groups of the Neanderthals left behind numerous stone implements of the Middle Palaeolithic epochs and animal bones.

The inhabitant of Aachen and Master Builder, Couven, constructed the building in 1783 following the model of a townhouse of the nobility for the cloth manufacturer, M.P.W. Troistorff. In an acceptance of the times, the half-timbered house was plastered and decorated with ornamentation. Rich carvings in the doors with supraports and artistic wrought-iron works in the banister and balcony railing testify to the splendour and prosperity of the inhabitants.
