History

In the early history of Rio de Janeiro, the nucleus of the city was surrounded by swamp

 attempted to build canals, but the construction was always hampered by technical and financial difficulties. By the end of the 17th century there were only a few hundred metres of canalisation completed.

After 1706, construction of the aqueduct was given a fresh impulse by colonial authorities. During the rule of governor Aires de Saldanha (1719–1725) it was decided that the canals, which at the time reached the Campo da Ajuda (today's Cinelândia square

. The aqueduct was inaugurated in 1750.

The most impressive feature of the aqueduct is the course that connects the hills of Santa Teresa and Santo Antônio, in today's Lapa neighbourhood. This segment of the aqueduct spans 270 metres and consists of two storeys of monumental arches - 42 in total - with a maximum height of 17.6 metres.

In colonial times, water from the Carioca Aqueduct reached several fountains scattered through Rio de Janeiro, including those in Santo Antônio Square, Ajuda Square (Cinelândia

) and the Terreiro do Paço (today's Praça XV). At the end of the 18th century, as the waters of the Carioca river were insufficient to feed the aqueduct, water from other streams were also derived to its canals.

Tramway

The aqueduct was deactivated at the end of the 19th century, as new alternatives to supply water to Rio were developed. The arches were adapted in 1896 to serve as a bridge for a tram

 - the Bondinho de Santa Teresa (Santa Teresa Tramway) - that transports passengers between the centre of Rio and the hilly Santa Teresa neighbourhood. The picturesque ride is popular among locals and tourists alike. The Santa Teresa bondinho is the only tram still in use in Rio de Janeiro.

In the 1960s, several houses that had been built near the aqueduct were demolished, improving the visual impact of the monument.
