Washington Street in Watertown. The house was built as a rest home for Watertown's aged population. The Keep Home's main benefactor was Emma Keep-Schley, who (along with Rosewell, George and Anson Flower) dedicated the home to her late husband Henry Keep.
A modern facility, known as the Samaritan Keep Home, was built next of the mansion in 1972. The mansion was demolished. The Henry Keep Apartment Complex was then built on this site soon after.
