One of the five oldest houses in Connecticut is the Bushnell Farm house at 1445 Boston Post Road in Old Saybrook. It began as a two room, one story, thatch roofed post and beam house built by the Elder Joshua Bushnell. It is listed in the National Register of Historic Places as the Elisha Bushnell House and J. Frederick Kelly, in his classic Early Domestic Architecture of Connecticut (1924), calls it the Older Bushnell House. The house was expanded over the two centuries that the Bushnell family owned it. The property has a number of outbuildings, including an early eighteenth-century barn, a loom house (the Bushnells were both farmers and weavers) and a building referred to as the slave house. Maintained as a private residence in an excellent state of preservation, the property is often opened to schools, historical societies and the Connecticut River Museum Summer Camp.
