The Shepherdstown Lodge holds a claim to fame through an object held in its keeping for nearly two hundred years: George Washington's Masonic Apron. One of the two owned by the former president, the apron was a gift from the Marquis de Lafayette during the Revolutionary War on behalf of the Grand Lodge of France. After Washington's passing, the apron was given to his youngest brother Charles, who passed it on to Captain Thomas Hammond, who had married his daughter, Mildred Washington. Captain Hammond would become a member of the Shepherdstown Lodge in 1815 and Master in 1848. Following his initiation, he presented the Lodge with the apron, where it remained perfectly preserved until 2011.
The Lafayette Apron was worn in the cornerstone laying ceremony of several building projects in Washington D.C., including the Smithsonian Institution in 1847 and the Washington Monument in 1848. The apron was put on public display during the Shepherdstown Lodge's bicentennial celebration, where visitors were permitted inside of the Lodge to see it and take photographs. Currently, the Lafayette Apron is on loan to the Mt. Vernon estate, where it has been displayed every year on George Washington's birthday.
