The majestic stone chamber of the Patriarchal’s Reservoir lies below Praça do Príncipe Real. This tank was constructed between 1860 and 1864 and became a key element in the water distribution network throughout the lower area of Lisbon. It displays an octagonal shape and consists of 31 pillars measuring 9.25 meters that support the ashlar arches. These arches hold the vaults, granting an atmosphere of grandeur to the space. The water for the reservoir was supplied by the Águas Livres Aqueduct until its deactivation in 1949. Currently, the complex provides underground access to the Loreto Gallery, with an extension of 410 meters, leading to the São Pedro de Alcântara Garden.
