The Mercedes-Benz Museum is an automotive museum housed in Stuttgart, Germany. Stuttgart is home to the Mercedes-Benz brand and the international headquarters of Daimler AG. The current building, which stands directly outside the main gate of the Daimler factory in Stuttgart, was designed by UN Studio. It is based on a unique cloverleaf concept using three overlapping circles with the center removed to form a triangular atrium. The building was completed and opened on 19 May 2006.
