Notre-Dame de Reims, known in English as Reims Cathedral, is a Roman Catholic cathedral in the French city of the same name, the archiepiscopal see of the Archdiocese of Reims. The cathedral was dedicated to the Virgin Mary and was the traditional location for the coronation of the kings of France. Reims Cathedral is considered to be one of the most important pieces of Gothic architecture. The cathedral, a major tourist destination, receives about one million visitors annually. It became a UNESCO World Heritage Site in 1991.

The cathedral church is thought to have been founded by the bishop Nicasius in the early 5th century. Clovis was baptized a Christian here by Saint Remigius, the bishop of Reims, about a century later. He was the first Frankish king to receive this sacrament. Construction of the present Reims Cathedral began in the 13th century and concluded in the 14th century. A prominent example of High Gothic architecture, it was built to replace an earlier church destroyed by fire in 1210. Although little damaged during the French Revolution, the present cathedral saw extensive restoration in the 19th century. It was severely damaged during World War I and the church was again restored in the 20th century.
