A bit of history

The Aqueduto da Usseira dates back to Roman times, though its exact construction period is uncertain. It was part of a water supply system that served the Roman settlement of Eburobrittium, which later became Óbidos. The aqueduct's arches and channels were built using local stone, and remnants of the original structure remain visible today.
