[4] Greenburgh developed along the Hudson River, long the main transportation route.

It was settled by northern Europeans in its early years, primarily of Dutch and English descent.

The Romer-Van Tassel House served as the first town hall, from 1793 into the early 19th century.

[6] The Spanish American War Monument to the 71st Infantry Regiment in Mount Hope Cemetery was added to the National Register of Historic Places in 2011.

[8] The Tappan Zee Bridge connects Tarrytown in Greenburgh with South Nyack in Orangetown, New York.

[14] Roughly half of Greenburgh's population reside within the town's six incorporated villages.

The Metro-North Railroad's Hudson Line passes through the west of the town with stations at Hastings-on-Hudson, Dobbs Ferry, Ardsley-on-Hudson, Irvington and Tarrytown, and its Harlem Line passes through the east of the town with a station at Hartsdale.

It consists primarily of unincorporated parts of the town of Greenburgh, but is also commonly considered to include adjoining parts of the villages of Irvington and Tarrytown which branch off from East Sunnyside Lane and Mountain Road.

[6]) East Irvington was formerly known as "Dublin"[19] from the population of Irish immigrant laborers there who worked on the large estates in the area, on the railroads and docks, or in the stone quarries, the remnants of which still exist.
