This is a historic aqueduct in the city of Lisbon, Portugal. It is one of the most remarkable examples of 18th-century Portuguese engineering, including the largest stone arch in the world. The main course of the aqueduct covers 18 km, but the whole network of canals extends through nearly 58 km. The Mãe d'Água (Mother of the Water) is a reservoir of the Amoreiras. It is now deactivated and can be visited as part of the Museu da Água (Water Museum).
