SpainA Roman buttress dam complex in Navarra, Spain, consisting of two dams dating to the 2nd and 3rd-4th centuries AD respectively. The structure featured a notably thin 0.9 m dam wall reinforced by buttresses, though this proved insufficient to prevent its eventual failure. It represents an important example of Roman hydraulic engineering on the Iberian Peninsula, where builders pioneered the use of arches and buttresses to stabilize dam walls.
