The Koblenz Gate or Michael Gate is part of the Electoral Residence Palace. The gate bridges the road to Koblenz. Elector Clemens-August had the gate built in 1751 - 57. It served the Order of the Knights of St. Michael as an archive and meeting room. In the lateral gate passages there used to be guard and customs rooms. The pairs of strongly emphasized columns are striking, which in connection with the electoral coat of arms cartouche give the gate a particularly representative character. Above are the personifications of the four virtues of the Order of St. Michael: piety, perseverance, fortitude and fidelity. The centerpiece is the gilded lead casting of the Archangel Michael.
