Henry Austin, now known as Betts House and home to
Yale University's international initiatives. • The

A. Whitney Griswold Other historic districts In addition to the main Prospect Hill Historic District, the neighborhood planning zone includes the
Hillhouse Avenue Historic District, an area adjoining Downtown New Haven south of Science Hill, and part of
Edgerton Park. Because the neighborhood planning zone eastern boundary runs along Whitney Avenue, a row of houses on the west side of the
Whitney Avenue Historic District of
East Rock is technically also within the neighborhood planning zone. ==Demographics==
