Saint-Fiacre is a commune in the Seine-et-Marne department in the Île-de-France region in north-central France. It is named after Saint Fiacre who built a hospice for travelers at the end of the 6th century in what is now Saint-Fiacre, Seine-et-Marne. He is still revered as the patron saint of Saint-Fiacre. In the late medieval song Le Roy Engloys, Saint-Fiacre en Brie, Brie being the region the town is located in, is mentioned as the place where the English king Henry V died. This is incorrect, however, as the king died at Vincennes, the error can be explained by the fact that the song has been written a century later.
