The old Carioca Aqueduct is one of the most iconic symbols of old Rio, preserved in the Lapa neighborhood. Built in the 18th century in Romanesque style, it transported water from the Carioca river to supply the population. The structure’s 42 double arches are recognized worldwide and remain a top postcard image. Today, it serves as the track for the tram to Santa Teresa. When snapping a photo, try to include Circo Voador just behind.
