Fodor's Expert Review Cathédrale

This vast, frigid edifice was built in the 1740s in a ponderous Baroque style, eased in part by the florid ironwork of Jean Lamour. The most notable interior feature is a murky 19th-century fresco in the dome. The Trésor (Treasury) contains minute 10th-century splendors carved of ivory and gold but is only open to the public on rare occasions.
