Origin and history

The hotel of the Royal Mission, located in Nancy in the Grand East region (former Lorraine), was founded in 1739 by Stanislas Leczcynski, king of Poland and Duke of Lorraine. The latter entrusted the plans to architect Emmanuel Heré, and the construction was completed between 1741 and 1742. The building, inaugurated on February 2, 1743, served first as an apostolate for the Royal Missions, before becoming a major seminary. Today, it is home to Sciences Po Paris' nean campus dedicated to German studies.

The facades, the stone staircase with wrought iron ramp, the vestibule lantern, and the bishop's living room (woodworks, ceiling, paving and marble fireplace) were listed as historical monuments in 1940. A further classification in 1997 protected roofs, stairwells and vestibule, excluding a 19th century gallery. These protections highlight the architectural richness of the building, combining Baroque and classical elements.

The former church of St Peter, integrated into the complex, bears witness to the original religious vocation of the place. In 2000, the Institut d'études politiques de Paris set up its office there, marking a successful heritage conversion. The building thus combines Lorraine's history, spiritual heritage and educational modernity, while remaining a symbol of Stanislas Leczcynski's enlightened patronage.

The official address, 94-96 avenue De-Lattre-de-Tassigny (formerly rue de Strasbourg), square the hotel in the heart of Nancy, a city marked by its eighteenth century heritage. The current public property guarantees its preservation, while elements such as vaulted galleries or interior decorations recall its original fascist.
