Introduction
El Zanjón de Granados is an 18th-century colonial house in San Telmo whose restoration uncovered an underground network of tunnels — remains of the early drainage channels ('zanjón') and passages of the young city. Now a museum, it lets visitors descend beneath the house to follow the brick-vaulted tunnels and trace Buenos Aires' earliest urban history.
