Champlieu: a Gallo-Roman site accessible free of charge
Located in the Oise department, the ruins of Champlieu are a fascinating archaeological site that offers a rare glimpse into Gallo-Roman life in France. This historic site possesses invaluable cultural and historical wealth.
History of Champlieu
The Gallo-Roman site of Champlieu is located on the Roman road or Brunehaut road. The site, owned by the Oise Departmental Council, is in the commune of Orrouy, about twenty kilometers from the towns of Senlis and Compiègne.
Champlieu was once a vicus, a small Gallo-Roman rural settlement, located on a strategic Roman road linking Senlis to Soissons. It is a small ancient town that developed from the 1st century BC to the 4th century AD, and the ruins of its monumental center can still be visited today: its temple measuring 22 m on each side, its theater with a capacity of over 3000 seats, and its baths.
Founded in the 1er century AD, this site flourished for several hundred years before being abandoned during the 3rde century.
An archaeological discovery
The archaeological site of Champlieu, known in writings since the 16th centurye century as a Roman camp was discovered in 1857, during excavations carried out by Eugène Viollet-le-Duc and then Albert Roucy. This site, dating from the XNUMXnde century AD, was then part of the monumental center of an ancient secondary settlement composed of a temple, a theater and thermal baths.
One of Champlieu's most remarkable discoveries is the Gallo-Roman theater. With a capacity of approximately 3 spectators, this theater is a typical example of Roman architecture. The semicircular layout and stone tiers are still clearly visible, giving an idea of the scale and organization of the shows of the time.
The ruins of the Roman baths are also present on the site. These public baths were a central part of Roman social life, providing facilities for bathing, relaxing, and socializing. The remains of the various spaces, such as the frigidarium (cold room), the tepidarium (warm room), and the caldarium (hot room), provide insight into the complex functioning of these infrastructures.
Another key feature of the Champlieu site is the temple dedicated to Roman deities. This sanctuary, although partially in ruins, preserves important architectural elements, including columns and pillar bases. The temple was likely a central place of worship for the inhabitants of Champlieu, where religious rites and ceremonies took place.
Champlieu: a place of passage and conviviality
