It is the lord of Ognon, who making his staff march according to a well-established ceremony,
gave rise to the saying "défiler en rangs d'oignons" (march in rows of onions) as a play on words.
This 18th century castle, now destroyed, was seriously damaged during the First World
War, for it served as a military hospital. All that remains are the outbuildings,
now a private property, with a magnificent estate adorned with statues and an
immense ornamental lake called "the Mirror".
Some of the allied soldiers who died at the hospital in the First World War are buried in
a cemetery, which has been renovated with taste and respect.
The parish church with no original features, dedicated to Saint Martin, rebuilt in
17th century, is only distinguished by its portal with bossing.
The far west of the district, covered with the Halatte forest, contains vestiges
of a Gallo-Roman Healing Temple used from 1st to 5th century. It can be reached by a
marked forest path from the N32 parking area (identification sign). The statues and almost
400 stone ex voto discovered on the site are exhibited at the Art and Archaeology Museum of Senlis.
