High Bridge, Croton Aqueduct — Stereoscopic View (1864)

Stereoscopic photograph of the High Bridge carrying the Croton Aqueduct over the Harlem River, from the Robert N. Dennis collection. Stereoscopic views were the 3D photography of the Victorian era — viewed through a handheld device, they created a striking illusion of depth. The High Bridge's Roman-style stone arches made it one of the most popular stereoscopic subjects in New York.
