The Abbey of Signy was a Cistercian monastery founded in 1135. After the French Revolution, it was sold as national property, and then entirely demolished. The Salle Guillaume de Saint-Thierry, installed on the site of the Abbey in a restored wing of a 19th-century spinning mill, presents an exhibition on the monastic domain and life, the buildings of the historical abbey, and the archaeological excavations. The Association of the Friends of Signy Abbey works to ensure the cultural and tourist management of the vestige of the historical Signy Abbey.
