In the geologic timescale the Ypresian is the oldest age or lowest stratigraphic stage of the Eocene. It spans the time between 56 and 48.07 Ma, is preceded by the Thanetian Age and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the Lower Eocene.
Insider tip — Pierrefonds sits at the edge of the Compiegne Forest north of Paris, dominated by a spectacular restored medieval castle that Viollet-le-Duc rebuilt for Napoleon III. The thermal spring here has a long wellness tradition rooted in the forested Oise countryside. After a thermal session, explore the forest on horseback or visit the World War I armistice clearing nearby.
