Just one of several buildings in Concord that the Thoreau family called home, they lived in the building to the right of the main entrance while Henry was attending Harvard from 1833 to 1837. Later in the Century that part of the building was a boarding house and small hotel called “Thoreau Girls”, named after his aunts who lived there at one time.
