Archaeologists have discovered an unusual horseshoe-shaped monument and a collection of weapons and ornaments spanning multiple historical periods at a site in France.

Located in Marliens, a commune in eastern France, the site has a large bowtie-shaped structure, whose middle sports a circular construction measuring 36 feet (11 meters) in diameter. This center circlet is interconnected by a 26-foot-long (8 m) horseshoe-shaped structure on one side and a jug-handle-shaped feature on the other, according to a translated statement from the French National Institute of Preventive Archaeological Research (INRAP), which carried out the excavations.
