Ephraim Hammond House

The Ephraim Hammond House, also known as Cedar Hill, is a historic Georgian-style house located at 265 Beaver Street in Waltham, Massachusetts. Built in 1775, it is notable for being Waltham's only side-hall Georgian house and was added to the National Register of Historic Places in 1989. In the 19th century, it became part of the Cedar Hill estate owned by Cornelia Lyman Warren and was later donated to the Massachusetts council of the Girl Scouts of the USA. The house has been restored and now serves as a service center for the Girl Scouts, making it a unique site for both historical interest and community service.
