A route through one of the oldest galleries of the Águas Livres Aqueduct and the first of this system to be built (from 1746 onwards). The gallery began a few metres before the Arco das Amoreiras and supplied the São Pedro de Alcântara and Loreto fountains, ending at Largo do Diretório in front of the Teatro de São Carlos. Its various branches supplied fountains, factories, convents and some noble houses.
