After repeated efforts, the Dukes of Lorraine succeeding in having their capital made a primal see in 1602. However, the present cathedral was only built in the first half of the 18th century. Several famous architects participated in the construction. Giovanni Betto designed a plan inspired by the one found in Roman churches, which was simplified by Hardouin-Mansart. Boffrand then made further changes, and the final result was typically classical. Inside, there is little decorative sculpture and the vaults are free of ornamentation. On the other hand, at the crossing of the transept, a flattened cupola is covered with a fresco in honour of the Heavenly Glory. The church has a well-balanced facade. At the top of the central section, there is a cornice which replaced a triangular fronton after the initial project to build a dome was abandoned. Two square towers frame the central section. They are mounted by octagonal pavilions topped with egg-shaped domes that Victor Hugo called « the Pompadour pepper boxes ». Inside the church, a wooden Christ on the Cross is attributed to Ligier Richier. The organ console and the chapel grilles are Rococo. The Treasury contains liturgical objects from the 10th century which belonged to Saint Gauzelin, bishop of Toul.
