The Royal Wedding


The wedding of Prince Guillaume and Countess Stéphanie de Lannoy was held on 20 October 2012 at the Cathédrale Notre–Dame in Luxembourg. Their marriage was attended, among others, by foreign monarchs from several countries. The wedding took place in an atmosphere of national celebration with fire-works, and concerts while a locomotive travelled through Clause adorned with giant wedding bands and portraits of the couple. Late into the night, the people of Luxembourg were treated to a wonderful romantic evening and the rest of the world still remembers their big day with fan pages on the internet, newspaper articles and videos of the ceremony creating a buzz on the web.
