Founded by the Romans, Rouen is situated amidst the chalk cliffs along the Seine and filled with half-timbered houses and exquisite Gothic architecture. The old city on the right bank of the river is surrounded by a natural amphitheater of hills. Highlights include the Justice Palace and 15th-century Aître Saint-Maclou, a rich example of flamboyant Gothic architecture. The city is known for its role in the heroic tragedy of Joan of Arc, patron saint of France. Tried and condemned for heresy, she was burned alive at the stake in Rouen’s Old Marketplace in May 1431.
