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 Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site.
