The Patriarchal’s Reservoir – Water Museum

Hidden beneath the Príncipe Real Gardens lies the Patriarcal Reservoir. Designed by the French engineer Louis-Charles Mary in 1856, it was completed eight years later. It was one of the first reservoirs and the most important in the water distribution network of the lower part of the city. Initially it was supplied by the Águas Livres Aqueduct, and from 1890 by the Alviela Aqueduct. It was decommissioned in 1949. Its octagonal shape matches that of the upper lake, and it provides underground access to the Loreto Gallery, connecting the reservoir to the São Pedro de Alcântara Garden.
