The Salles des Croisades is a set of rooms located in the north wing of the Palace of Versailles.
The rooms were created in the mid-19th century by King Louis-Philippe for his museum of French history, and opened in 1843, at a time when France was seized with enthusiasm with its historical past, and especially the Crusades period. The rooms are filled with over 120 paintings related to the Crusades. King Louis-Philippe included the names of the thousands of family whose ancestors went to the Crusades, encouraging many forgeries at that time.
