Place Stanislas, Place de la Carrière and Place d’Alliance in Nancy

Nancy, the temporary residence of a king without a kingdom – Stanislas Leszczynski, later to become Duke of Lorraine – is paradoxically the oldest and most typical example of a modern capital where an enlightened monarch proved to be sensitive to the needs of the public. Built between 1752 and 1756 by a brilliant team led by the architect Héré, this was a carefully conceived project that succeeded in creating a capital that not only enhanced the sovereign's prestige but was also functional.
