Step-by-step explanation:
The manmade feature in New York City that was meant to bring a quiet open space to its citizens is Central Park.
Designed by Frederick Law Olmsted, Central Park was built in 1858 and aimed to serve as an oasis for city dwellers, offering a chance to experience nature and obtain a sense of peace amidst the urban environment.
The development of such green spaces was influenced by the belief in the restorative power of nature held by the nineteenth-century middle and upper-middle classes, and the subsequent City Beautiful movement championed well into the twentieth century by leaders such as Olmsted and Daniel Burnham. Central Park is a testament to these urban planning principles, incorporating larger park areas within the city to provide a respite from the urban sprawl.
