The Unfinished Monument: The Aqueduct of Maintenon

The Aqueduct of Maintenon, an ambitious unfinished work, sprawls across the Château de Maintenon's domain. Instigated by Louis XIV in 1686, as part of the Canal de l'Eure, this colossal structure was to transport water from the Eure river to Versailles. As the thirst for water grew at Château de Versailles, local rivers and streams were found wanting. Various proposals surfaced to address this issue, but the architect of Louis XIV, Vauban, was overlooked by Louvois. The latter championed the construction of an aqueduct, feeling it would be a grander engineering marvel. Work on this unfinished aqueduct began in 1686, only to be halted in 1689, amidst the war against the League of Augsburg.
