The Place Stanislas, known colloquially as the place Stan', is a large pedestrianized square in Nancy, Lorraine, France. Since 1983, the architectural ensemble comprising the Place Stanislas and the extension of its axis, the Place de la Carrière and 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 Stanisław Leszczyński, former king of the 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'd surrounded himself by artists and architects including Germain Boffrand, who trained Emmanuel Héré: hence Stanisław 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 Stanisław Leszczyński as a way to link the medieval old town of Nancy and the new town built under Charles III in the 17th century. The square would also be a place royale to honour his son-in-law, Louis XV. The design linked two handsome buildings that already existed, the Hôtel de Ville, now centred on its grand square, and the Hôtel du Gouvernement. The seat of city government and the seat of ducal government faced one another as complements through a series of rational, symmetrical, yet varied urban spaces unequalled in Europe at the time.

Saint Nicholas (Greek: Ἅγιος Νικόλαος, Hagios ["Saint", literally "Holy", Latin: Sanctus] Nicolaos ["victory of the people"]) (270 – 6 December 343), also called Nikolaos of Myra, was a historic 4th-century saint and Greek Bishop of Myra (Demre, part of modern-day Turkey) in Lycia. Because of the many miracles attributed to his intercession, he is also known as Nikolaos the Wonderworker (Νικόλαος ὁ Θαυματουργός, Nikolaos ho Thaumaturgos). He had a reputation for secret gift-giving, such as putting coins in the shoes of those who left them out for him, and thus became the model for Santa Claus, whose modern name comes from the Dutch Sinterklaas, itself from a series of elisions and corruptions of the transliteration of "Saint Nikolaos". His reputation evolved among the faithful, as was common for early Christian saints. In 1087, part of the relics (about half of the bones) were furtively translated to Bari, in southeastern Italy; for this reason, he is also known as Nikolaos of Bari. The remaining bones were taken to Venice in 1100. His feastday is 6 December [O.S. 19 December].
