L’église Saint-Léger

The foundation of the parish of Delle, whose patron saint is Saint Léger, probably dates back to the Carolingian period, but the primitive church no longer exists.
The building was then radically modified in 1709 and the flood of September 1714 caused a lot of damage, especially to the bell tower, which had to be demolished. The building, completed in 1744 on the south side by an outer chapel dedicated to Saint Francis Xavier, was again largely destroyed by fire in 1857, which had to rebuild it almost entirely

The church of Saint-Léger in Is-sur-Tille has an original silhouette due to its turbulent history. Built in the 14th century on the site of an older place of worship (as evidenced by the discovery of Merovingian sarcophagi in the 1960s), it has been rebuilt several times. Around 1420, it was surrounded by a wall with 9 towers to use it as a refuge from invasions. It was rebuilt in the 16th century and in 1620 the bell tower collapsed. The need to rebuild the tower quickly probably explains the unusual choice of location and the irregularity of the pediment on the façade. Further work took place in the 18th century. More recently, between 2007 and 2009, the church was rehabilitated and its external and internal appearance renovated. The bell tower is covered with glazed tiles typical of Burgundian architecture and houses three bells, the largest of which (baptized Louise) weighs 1802 kg.Source and more:burgund-tourismus.com/kirchen-abteien-und-andere-religioese-bauwerke/eglise-saint-leger
