The Château de La Desnerie in La Chapelle-sur-Erdre, Loire-Atlantique, represents a layered architectural heritage spanning from the 15th century. Originally held by the Leet family since the late 14th century, it passed to the La Roche-Saint-André family in 1552, who substantially enlarged the estate and added a private chapel in the 1620s-1630s. In the 18th century, further expansion included the western wing designed by architect Jean-Baptiste Ceineray. Listed on the Supplementary Inventory of Historic Monuments since 1985, this private estate reflects the evolution of noble residential architecture through multiple periods, preserving its historical interiors and gardens as a significant example of regional patrimony.
