Mount Vernon Place is a short, dead-end street in Boston’s Beacon Hill neighborhood. The street was once an entire block of eight rowhouses, and was developed in the 1830s on land formerly owned by John Hancock and his family. The residences numbered 1-5 Mount Vernon Place were torn down during the 1910s to accommodate the expansion of the landscaped grounds of the State House, leaving just 6, 7, and 8 Mount Vernon Place. The center rowhouse, 7 Mount Vernon Place, was built in 1834 and is believed to have been designed by Alexander Parris, a prominent local architect who designed Quincy Market and mastered the Federal and Greek Revival architectural styles with many notable buildings all over the east coast. The residence has a three bay facade and brownstone sills, lintels, and door surround and has been preserved for nearly two centuries. The house was long-owned by George W. Lyman, an industrialist who lived nearby on Joy Street. The residence was rented for decades until it was purchased by Francis C. Gray a physician, and inherited by his grandson, Ralph Weld Gray, an architect through the 1940s.
