Église Saint-Sébastien de Nancy, Baroque church in Charles III Square, Nancy, France.

The Église Saint-Sébastien is a Baroque church on Charles III Square featuring a curved facade with twin towers and sculptural details. Inside, the wide nave is divided by carved columns and topped with elaborate vault decorations that create a sense of height and space.

The parish was created on 21 November 1593, when Duke Charles III founded Nancy's Ville-Neuve. A first chapel, built in three months in 1603, was replaced from 1720: Jean-Nicolas Jennesson kept the 1682 tower, added a second, and completed the church in 1731. Bishop Scipion-Jérôme Bégon consecrated it on 9 August 1732.

Saint Sebastian was invoked against the plague that ravaged the region, which explains the church's dedication. On the facade, reliefs by Joseph-Dieudonné Pierre show the Saviour and the Virgin around the door, with Saint Nicholas and Saint Charles at the ends. Statues of Saint Sebastian and Duke Leopold stand on the two side bays.

The church sits centrally on Charles III Square and is easy to reach on foot from the city center. Visiting times vary based on religious services, so checking ahead helps plan your visit more smoothly.

The two 45-metre towers, topped with lanterns and crosses, are attributed to Jean Lamour, the master ironworker who made Nancy's Place Stanislas railings. The clock on the facade dates from the 19th century and replaced the arms of Lorraine, which were hammered down in 1792.
