The most recent addition to the Museu da Água is the Galeria do Loreto (‘Loreto Gallery’), which connects the Reservatório da Patriarcal with the São Pedro de Alcântara garden.  The Galeria do Loreto has a total length of 2835 m and a public tour is now available of a part of gallery (around 400 meter). There are plans to open up other parts of the gallery.
