Anyone passing through Lapa might not imagine that the structure of old colonial arches was designed and functioned as an aqueduct, responsible for supplying the city with water from the Carioca river. It was a work of great importance for urban development: before the aqueduct, enslaved people had to travel long distances to the mouth of the Carioca river to fetch water.
The water distribution works began in 1719 with the channeling of the Carioca River's springs. By 1723, the work was completed, but in 1744 Governor Gomes Freire ordered its reconstruction. The order came because the previous structure, built with iron pipes, had not withstood the effects of time or weather conditions. The new project used the technique of mixing stone and lime with whale oil, forming an extremely resistant concrete alloy.

Built by enslaved African and Indigenous labor, the Carioca Aqueduct was completed in 1750, with the arches being its most visible part. In total, the water supply system stretched about 8km, carrying water from the slopes of Corcovado to the Carioca fountain, at the foot of the Santo Antônio Convent.

Recorded by both Brazilian and foreign artists as a symbol of modernity, utility and beauty, the Carioca Aqueduct gradually became obsolete for urban water supply in the mid-19th century, due to urban expansion, the channeling of other rivers, and the emergence of new supply possibilities. But the structure did not lose its importance. Starting in 1896, the Arcos began to be used as a viaduct for the new iron trams of the Companhia de Carris Urbanos, the main means of access from downtown to the heights of the Santa Teresa neighborhood. The trams were, at the time, the most modern form of urban transport available.

From aqueduct to viaduct, the Arcos became one of the city's most famous postcard images. With the creation of IPHAN in 1938, the structure was granted heritage status and became part of the country's historical, cultural, and natural heritage.
