Roman aqueduct of Vieu

A subterranean aqueduct, it stretches from Champagne-en-Valromey to the Adoue fountain in Vieu.

The aqueduct has been the subject of historical studies since the seventeenth century. In 1820, Jean Anthelme Brillat-Savarin, who owned a property in Vieu-en-Valromey, also studied the aqueduct^{[citation needed]}.

According to R. Chevallier, a member of Robert Bedon's team, the dating of the aqueduct is uncertain, but estimated to be as old as about 150 AD^{[citation needed]}.
