The Cathédrale Sainte-Croix dominates the old town from across the Loire — a Gothic church of considerable scale, though the Gothic style is partly illusion, as much of what you see dates from the 17th to 19th centuries. The interior is long and light, with the proportions of a great medieval church but walls pierced by large windows that give it a more open feel than many older cathedrals.
The 19th-century stained glass is the main interior draw: a series of windows in the choir traces the story of Joan of Arc's 1429 campaign to break the English siege, from her departure from Vaucouleurs to her execution in Rouen. The carving on Joan's altar is also worth attention. The north and south towers, though Neo-Gothic in style, are fine examples of their period and can be climbed for views over the city.
