History

Ontario County was established in the late 18th century during New York State's early organization of counties. Over the 19th century it was reduced in size as new counties were created farther west, a common pattern in the settlement and administrative development of the state. Many towns and villages in the county retain 19th-century architecture and historic sites reflecting that era of growth.

Vineyards and wineries tied to the Finger Lakes wine region contribute to agritourism, while lakeside parks, cultural attractions and historic downtowns draw visitors. Proximity to Rochester also influences commuting patterns and regional economic links.
