Hidden underground the garden of Príncipe Real, you can find the Patriarchal Reservoir, whose construction was completed in 1864.
It was one of the first tanks of the distribution network, designed in 1856 by French engineer Louis-Charles Mary, which enabled the supply of water to the inhabitants of Lisbon.
The Patriarchal Reservoir, initially fuelled by Águas Livres Aqueduct and from 1890, by the waters of the Alviela Aqueduct, displays an octagonal shape, to coincide with the lake drawing at the top.
