Nancy (German Nanzig) is a city in the north-eastern French department of Meurthe-et-Moselle, and formerly the capital of the Duchy of Lorraine, and then the French province of the same name. Place Stanislas, a large square built between March 1752 and November 1755 by Stanislaw I to link the medieval old town of Nancy and the new town built under Charles III in the 17th century, is an UNESCO World Heritage Site.
