Overview

The Reservatório da Mãe d'Água das Amoreiras is a 18th-century stone reservoir that served as the terminal point for the Águas Livres Aqueduct system in Lisbon. Designed by architect Carlos Mardel, the structure is defined by its massive central water tank, which is five meters deep and holds up to 5,500 cubic meters of water. The interior features a vaulted stone ceiling supported by large pillars, creating a cathedral-like acoustic environment. The building now functions as an exhibition space often hosting art installations, video projections, and cultural events. It remains one of the most significant examples of civil engineering from the period of King João V's reign. Visitors can access the rooftop terrace, which provides panoramic views of the Amoreiras neighborhood and the surrounding city skyline. The reservoir's design incorporates high-relief sculptures and symbolic decorative elements reflecting its historical importance to Lisbon's water supply.
