Built in 1768 for a wealthy merchant, the Lee mansion is an extraordinary example of pre–Revolutionary Georgian architecture. Rococo woodcarving and other details complement historically accurate room arrangements; the most exciting feature for aficionados is the original hand-painted wallpaper. Ongoing restoration and interpretation by the Marblehead Museum place the 18th- and 19th-century furnishings and artifacts in context. The friendly guides welcome questions and are well versed in the history of the home. The gardens are open to the public. Across the street at 170 Washington St., the J.O.J. Frost Gallery and Carolyn Lynch Education Center (free admission, donations welcome) features paintings, wooden models, and carvings by the noted folk artist J.O.J. Frost, a Marblehead native. The Museum also operates the Civil War & G.A.R Museum, located within the Old Town House, open to the public on a limited schedule.
