Nancy, the temporary residence of a king without a kingdom – Stanislaw I 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. Since 1983, the architectural ensemble comprising the Place Stanislas, the extension of its axis, the Place de la Carrière, and the Place d'Alliance, has been on the list of UNESCO World Heritage Sites.
After the War of the Polish Succession in 1737, the Duchy of Upper Lorraine, of which Nancy was the capital, was given to Stanislaw I Leszczynski, former Ruler of Polish-Lithuanian Commonwealth and father-in-law to King Louis XV of France. An earlier ruler, Leopold, Duke of Lorraine, had undertaken a lot of reconstruction in Lorraine, which had been ravaged by a series of wars. He had surrounded himself by artists and architects, including Germain Boffrand, who trained Emmanuel Héré. Hence, Stanislaw found a pool of talent and experience to draw from on his arrival. The square was a major project in urban planning, dreamt up by Stanislaw I, as a way to link the medieval old town of Nancy and the new town built under Charles III in the 17th century.
In 1831, a bronze statue of Stanislas was placed in the middle of the square.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
