An experienced urban explorer knows that when an object appears unusual, it has a long history behind its appearance. One such example is the wall behind the 86th Street Shop in Central Park. This is where the Parks Department fuels and repairs its vehicles.
The wall behind the shop’s parking lot is slightly inclined and runs straight between the shop building and the Central Park Precinct. This wall is a remnant of Central Park’s Lower Reservoir, which contained the city’s drinking water from 1842 to 1929.
