Colline de Sion, also known as Sion-Vaudémont, is a geological and historical promontory in the Lorraine region of France standing at 545 meters above sea level. It is a cuesta, a distinct topographical formation characterized by a steep escarpment on one side and a gentle slope on the other. The site is home to the Basilica of Notre-Dame de Sion, a place of pilgrimage since the Middle Ages. Archaeological excavations have identified the location as a former Celtic oppidum occupied by the Mediomatrici tribe. The hill provides a panoramic vantage point over the Xaintois plain and the Moselle valley. The site features the 'Monument de Barrès,' a cenotaph dedicated to the writer Maurice Barrès. It is protected as a protected natural site due to its unique calcareous grassland flora. The hill serves as a crossroads for several regional hiking paths, including trails leading toward the nearby Vaudémont village ruins.
