Walnut Street in Boston’s Beacon Hill is one of the finest short streets that showcases some of the best examples of 19th century residential architecture in Massachusetts. Built in 1812, the house at 8 Walnut Street, is an excellent example of a Federal style mansion updated after the Civil War with new window sashes and projecting oriel window. The recessed off-center entrance consists of a front door which is flanked by multi-pane sidelights and surmounted by an elliptical fan light. On either side, columns support the cornice-headed entablature which disrupts the painted stone beltcourse between the first and second floors. The mansion was built by Uriah Cotting (1766-1819) a prominent real estate developer. When this house was completed, Cotting the property to Nathaniel Pope Russell, an insurance man who rented the property. Dr. George Parkman rented this house at the time of his tragic death at the hands of a Harvard Medical School professor in 1849. Mrs. Parkman and their son, John E. Parkman resided here until after the trial, when they moved to a larger residence on Beacon Street.
