It is located northeast of Troy on New York State Route 40, which is named Speigletown Road in that section.
In May 1976, the land was surveyed and the original name of Dort was changed to Speigletown.
The hamlet received its name from the Vanderspiegel[1] families, early Dutch settlers of the southern part of the Schaghticoke area.
Technically, Speigletown was at the intersection of the Northern Turnpike and what would become Fogarty Road.
Today's lower Speigletown originally consisted of lands owned by Bedford Filkins on the western side of the Northern Turnpike and Cornelius Lansing, which was sold to Ai Pine in 1856.
