I visited this tentative WHS several times as a pleasant stopover city on my way to other WHS or tWHS such as Mont-St-Michel, Le Havre, Amiens, Carnac or Cordouan. However, back in June 2011, I had allowed a full weekend specifically for Rouen.

Rouen is the capital of Normandy, even though it is relatively close to Paris. In the past it was one of the largest and most prosperous cities of medieval Europe and it was the seat of the Exchequer of Normandy during the Middle Ages. It was also one of the capitals of the Anglo-Norman dynasties, which ruled both England and large parts of modern France from the 11th to the 15th centuries. Rouen saw the tragic end of Saint Joan of Arc’s life, a legacy that continues to leave its mark in the city.

The highlights of this urban ensemble are its stunning churches, mostly constructed in Gothic style. The Notre-Dame Cathedral is by far the most elaborate and captivating and holds the title of the tallest cathedral in all of France thanks to the spire of the Tour Lanterne which is a must-visit if only for the panoramic view over the city. Inside the cathedral is where the embalmed heart of Richard the Lionheart rests in his tomb. The city’s others churches shouldn’t go unnoticed either: namely the Church of Saint-Maclou which is renowned for its five gabled arches on its facade, and the Abbey of Saint-Ouen which is a prime example flamboyant Gothic architecture.

The heart of Rouen lies undoubtedly around the Old Market Square and the Gros-Horloge, a stunning Renaissance clock and a symbol of the Norman town. If you have more time to spare and are travelling by car, I'd also recommend a quick visit to the nearby town of Jumièges which is known for its ruins of a former Roman Catholic abbey, and to Lyons-la-Forêt, named one of the most beautiful villages in France.

All in all, Rouen is one of France's pleasant cities but overall I feel it wouldn't add anything new to the WH list.
