Roman Catholic Cathedral, Notre-Dame de Senlis is the perfect example of Gothic architecture whose construction began in 1153 on the site of older sanctuaries.

Consecrated in 1191 by William to the White Hands, the archbishop of Reims, its construction lasted forty years. It was subsequently strongly modified during the following centuries and eventually received its heart with neoclassical decoration in 1777.
Classified as a historical monument, it remains, despite its modest size of 76 meters, one of the first and most beautiful Gothic monuments in France.
