Agua de Prata Aqueduct (Silver Water Aqueduct), Evora

The Silver Water Aqueduct was constructed during the reign of King João III. This intricate feat of architecture was designed to provide the city of Évora with a reliable water supply. The aqueduct was inaugurated in 1537 and remains a functional conduit for water even today, making it a rare example of an engineering marvel from its era that still serves its original purpose.

The aqueduct's origin point is the springs located in Graça do Divor, situated within the premises of the São Bento de Castris Convent. These springs, with their initial source traced to Herdade das Figueiras de Lobo, provide the water that the aqueduct channels to the city of Évora. The aqueduct stretches across an impressive distance of approximately 18 kilometers, showcasing the ingenuity and dedication of the architects and engineers involved in its creation.

The mind behind the Silver Water Aqueduct's design was none other than Francisco de Arruda, a royal architect of great renown. His vision and meticulous planning led to the successful realization of this water transportation system, which played a crucial role in sustaining the city's inhabitants. The aqueduct's construction commenced in 1531 under the direct orders of King João III, who recognized the significance of securing a consistent water supply for Évora.

The inauguration of the aqueduct on March 28, 1537, marked a significant achievement in engineering and infrastructure development. Its enduring presence has garnered it a rightful place on the UNESCO World Heritage List as an integral component of the Historic Center of Évora. Furthermore, its historical importance has led to its classification as a National Monument since 1910.
