I visited this WHS in June 2013. The cathedral's spiritual, religious and historical importance justifies it being on the list. Here, General de Gaulle and Chancellor Adenauer set the seal on reconciliation between France and Germany on 8th July 1962. The Former Abbey of Saint-Rémi did not impress me as a site of universal value while the Palace of Tau gave me a more in-depth overall experience. The sound and light show is really the cherry on the cake and is much better than the one organised in Strasbourg.
