Preserved and in full activity, Rio D'Ouro Reservoir, built in 1880, is an architectural jewel of Nova Iguaçu, located on a natural site covered by the Atlantic Rainforest. From its pavilion, there is a footbridge that crosses the reservoir and leads to a fountain made of cast iron designed by the French sculptor Albert-Ernest Carrier Belleuse. He was the designer of the torches of the staircase at the Paris Opera Theater as well as the professor of the acclaimed sculptor, Auguste Rodin.
Nymphs, carved in the foundries of Val D'Osne in France, guard the fountain adorned by twigs and the Brazilian coat of arms. With a sophisticated hydraulic engineering for the time of its implementation, Rio D'Ouro Reservoir is listed by INEPAC (State Institute of Cultural Heritage).
