One of the few surviving landmarks from the colonial era, this aqueduct was finished in 1750. At one time, Arcos da Lapa carried water down from Rua da Carioca; it now serves as a viaduct to the Bondinho de Santa Teresa (tram) that connects the downtown area to the Santa Teresa area. 270 meters (885.83 feet) in length and encompassing 42 arches, Arcos da Lapa is one of the most architecturally-significant structures in the area.
