Climbing 350 steps up to the 112m-high Tour Nord (aka Clocher Neuf; New Bell Tower) of the Cathédrale Notre Dame is well worth it. A 70m-high platform on the lacy flamboyant Gothic spire, built from 1507 to 1513 by Jehan de Beauce after an earlier wooden spire burned down, affords superb views of the three-tiered flying buttresses and the 19th-century copper roof, turned green by verdigris. Access is just behind the cathedral shop.
