The Sullivan Dorr House at 109 Benefit Street has been little altered since its completion in 1809. The building has a mixture of Palladian, Georgian, and Gothic detail that is fresh and original to Providence. The style is typical both of the architect, John Holden Greene, and of the date of its erection, a period when the stricter bonds of Colonial style were being broken. The house was built on the house lot and original burial site of Providence’s founder Roger Williams. It is an important landmark to the city for its historical associations and remarkable architecture.
