In the middle of a beautiful meadow at Rhense near Coblenz stands the famous historical "king's chair." Here, where the lands of the three great prelates of Cologne, Mayence and Treves join together, the princely Seven met to choose the new ruler who was to direct the destiny of the Holy Roman Empire.

Here Charles IV. was chosen by the free will of the Electors; here also the Seven elected Wenzeslaus of the house of Luxemburg, Charles' son, emperor. During his life-time Charles had exerted himself very much over the election of his first-born son, and he even made a pilgrimage with him to Rhense on the Rhine where, at the renowned "Königsstuhl," the chancellor of the kingdom, Archbishop of Mayence, often held important conferences with their Graces of Treves and Cologne, and the Count Palatine.
