The ruins of the Roman dam in Cuba are located near Cuba (Portugal) between Évora and Beja near the Nossa Senhora da represa chapel, in English: "Our Lady of the Dam ".
It is a curved wall that is reinforced on the outside by pillars (eight can be seen). It has been calculated that the pillars could not develop any structural effect because they are too far apart. Planned as a pillar or arch dam , the barrier structure functioned solely through the dimensioning of the dam as a gravity dam .
Above ground, only a section of the wall south of the stream that it dammed up in ancient times can be seen. Today it flows past the place where the wall broke. The wall, made of irregular quarry stone masonry , is 81 m long, 1.6 m wide and 1.8 m high in the middle. The dam could be connected to the nearby Roman villa rustica of São Cucufate .
