In the heart of Lisbon, at Praça das Amoreiras, 10, the Museu da Água is housed in the spectacular Reservatório da Mãe d’Água das Amoreiras, built between 1745 and 1834 according to the design of the Hungarian architect Carlos Mardel. This monumental underground reservoir is an integral part of the Águas Livres Aqueduct system, which has revolutionized the water supply of the Portuguese capital since 1746.

Inside, there is a large cistern about 7.5 meters deep, with a capacity of approximately 5,500 m³ and supported by imposing neoclassical columns created to provide visual rigor and harmony. The silence, the zenithal light, and the water reflection give this space an almost liturgical atmosphere.

The museum is part of a complex managed by EPAL, which also includes the Estação Elevatória a Vapor dos Barbadinhos – the main headquarters of the museum exhibition dedicated to the history of water supply and water-related technologies – and the Reservatório da Patriarcal, located underground in the Jardim do Príncipe Real.
