Fodor's Expert Review Cathédrale Notre-Dame-des-Doms
Built in a pure Provençal Romanesque style in the 12th century, this cathedral was soon dwarfed by the extravagant palace that rose beside it. The 14th century saw the addition of a cupola, which promptly collapsed. As rebuilt in 1425, the cathedral is a marvel of stacked arches with a strong Byzantine flavor and is topped with a gargantuan Virgin Mary lantern—a 19th-century afterthought—whose glow can be seen for miles around. Closed for renovation of the nave and entrance, the cathedral is slated to reopen in fall 2016.
