Dating back to the 12th century, this Gothic cathedral was the world’s tallest building for about five years – 1876 to 1880. But its beauty in changing light is what drew the impressionist artist, Claude Monet, whose work can be viewed at the Musee des Beaux-Arts de Rouen, to paint it several times. Today, the cathedral is one of the defining pieces of architecture in this part of Normandy. Aside from its striking architecture, it’s also famous for its tombs – one of which houses the heart of Richard the Lionheart.
