The small town of Willington is located on the western edge of Tolland County and is bordered by the Willimantic River on its west. Incorporated in 1727, the town remained agricultural in nature until the Industrial Revolution of the 1800s. Townspeople used the abundant waters of the Willimantic River for power and built woolen mills and a glass factory. Today, the town has returned to its rural nature with agriculture as its principal industry and is a bedroom community to larger surrounding towns. American historian, educator, and minister, Jared Sparks, was born in Willington. He served as President of Harvard University from 1849 to 1853.
