The Christopher Leffingwell House is unique in illustrating the development from 17th century beginnings to a mid 18th century town house. Built as a simple two room house in 1675 by Stephen Backus, the house later belonged to Thomas Leffingwell. In 1701 Thomas was granted permission to keep an inn. Benajah Leffingwell, Thomas' son, was also an innkeeper. The first additions to the original house were made to accommodate its use as an inn. The building descended to Christopher Leffingwell, a gentleman of utmost importance to the town and to the entire commonwealth. With his entrepreneurial skills and business connections he was invaluable as a supplier of provisions for the Revolutionary forces.
