Hillhouse Avenue in New Haven, Connecticut is lined with stunning 19th- and 20th- century mansions showcasing the evolution of styles and architectural taste for the wealthiest residents. This is the Graves-Dwight House, a high-style Italianate mansion built around 1862. The residence was built for John Samuel Graves (1807-1892), a local businessman and politician who was a founder of the New Haven Gas Light Company. The architect is not known, but the house is the work of a skilled designer with immense attention to detail. The highly ornamented exterior features a symmetrical facade, bracketed cornice and window hoods, a recessed third-floor balconette with segmental arch pediment above, and bold, period-appropriate paint scheme. The residence was later owned by James McLaren Breed Dwight, a lawyer, and his wife, Cora Tallmadge Dwight. Since the 20th century, the property has been owned and preserved by Yale University, and is now home to the Archaeology Department.

Town-Sheffield Mansion // c.1836-1957

One of the biggest architectural losses in New Haven was the 1957 demolition of the Town-Sheffield Mansion, formerly on Hillhouse Avenue. The mansion was built around 1836 by esteemed American architect and civil engineer Ithiel Town (1784-1844) as his own home on Hillhouse Avenue in the Greek Revival style; here he kept what was then an extraordinary architectural library, which was said to have been larger than any other personal collection anywhere at the time, including that of Sir John Soane in London. After Town’s death, the house was bought by Joseph Earl Sheffield in 1859, benefactor of the Sheffield Scientific School at Yale, and modified by local architect, Henry Austin in the Italianate Villa style. Alterations included two large asymmetrical towers, a new porch, and symmetrical side wings with large bay windows. After Sheffield’s death in 1889, the building was used for laboratory space for the school. Although the house was one of Austin’s most important works, it was demolished in 1957 by Yale to make way for Dunham Laboratory.
