are only opened when a governor leaves office, a head of state or the president of the United States comes to visit the State House, or for the return of flags from Massachusetts regiments at the end of wars. The tradition of the ceremonial door originated when departing governor Benjamin Butler kicked open the front door and walked out by himself in 1884.[source?] Incoming governors usually choose at least one past governor's portrait to hang in their office. Immediately before being sworn into office, the governor-elect receives four symbols from the departing governor: the ceremonial pewter "Key" for the governor's office door, the Butler Bible, the "Gavel", and a two-volume set of the Massachusetts General Statutes with a personal note from the departing governor to their successor added to the back of the text. The governor-elect is then escorted by the sergeant-at-arms to the House Chamber and sworn in by the President of the Senate before a joint session of the House and Senate.

Some walks have been modified with some past governors having their wives, friends, or staff accompany them. A 19-gun salute is offered during the walk, and frequently the steps are lined by the outgoing governor's friends and supporters. In January 1991, outgoing lieutenant governor Evelyn Murphy, the first woman elected to statewide office in Massachusetts, walked down the stairs before Governor Michael Dukakis. In a break from tradition, the January 2007 inauguration of Governor Deval Patrick took place the day after outgoing governor Mitt Romney took the lone walk down the front steps. Governor's residence Despite several proposals for establishing an official residence for the governor of Massachusetts, the Commonwealth of Massachusetts does not have a governor's mansion. In 1955, Governor Foster Furcolo turned down a proposal to establish the Shirley–Eustis House in Roxbury, built by royal Governor William Shirley, as the official residence. At one time, Governor John A. Volpe accepted the donation of the Endicott Estate in Dedham from the heirs of Henry Bradford Endicott. He intended to renovate the
