History
Its name comes from Nanciacos and first appeared in 1010 (Acts of the Abbot Engilbert). The territory belonged successively to the County of Sancerre and the area of La Chatre. Joan of Arc stayed there, leaving her name to the spring maiden. Its castle dates from the fifteenth century, and was rebuilt during the Renaissance.
