Roman aqueduct
Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts, sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout the Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire".

In the 1830s, officials in a rapidly expanding New York City saw a need for a larger water supply. Major David Bates Douglass was appointed to perform engineering studies on the future Old Croton Aqueduct in March 1833. Douglass made estimates for the new aqueduct in 1833–1834 and John Martineau performed a separate study in 1834. Both found the proposed route, which ran through the present-day park, to be okay. Thus, in 1837, construction started on the Aqueduct, which ran from the Croton River upstate to the New York Public Library Main Branch and Bryant Park in midtown Manhattan. The project was built by 3–4 thousand laborers who completed the entire aqueduct in five years. The aqueduct's builders constructed a gatehouse. within the present-day park to provide access to the aqueduct's interior. The old aqueduct was supplemented by the New Croton Aqueduct in 1890, which also ran through the park. The Old Croton Aqueduct was in use until 1955, though the part that ran through the park was closed down in 1897 after the new aqueduct was connected to the Jerome Park Reservoir.
