A lone triumphal arch in Soupir is all that remains of a château whose story spans medieval fortifications, aristocratic rebuilding, and Belle Époque extravagance. The original stronghold — “four towers, a drawbridge, a moat” — was already decayed when sold in 1456. The Baudoin family rebuilt its vast perimeter wall and hosted Fénelon in 1710, but by the mid‑18th century Antoine‑Séraphin Baudoin sold the estate to fund his Seven Years’ War expedition. Later owners suffered the destruction of the 1814–1818 Russian occupation.

The remains of the gate to the castle.
A renaissance came in 1873 when Pauline Plé, heir to the Piper‑Heidsieck fortune, transformed the manor into a Chambord‑inspired palace, doubling its size and modernizing the village. In 1906 it passed to Mary Boursin — born Marie Georget, once a boot stitcher and later the secret companion of Alfred Chauchard, founder of the Louvre department stores. She inherited his immense wealth, hosted lavish gatherings, and built the arch in 1908 with her initials.
Disaster struck in 1914: Mary’s daughter won a lawsuit for recognition, Calmette — to whom Mary had donated the château — was assassinated, and war obliterated Soupir. The château burned, was shelled, and vanished entirely by early 1915 along with the village. Mary died in 1921, leaving a fortune worth nearly €2.8 billion today. Calmette’s heirs sold the ruins and land for agriculture. Only the arch, a rusted gate, and traces of the moat survive — listed monuments standing alone in a field where the château once rose.
