The Charles Roberts Mansion in Beacon Hill maintains its architectural integrity and is an extremely rare example of the Egyptian Revival and Second Empire styles in Boston. The mansion was constructed in 1871 for Charles and Mercy Roberts, likely as a boarding house for transient legislators working at the Massachusetts State House nearby and other middle-class citizens. The mansion was designed by William Washburn, a prolific architect who lived nearby and is credited with iconic early Boston buildings like the Revere and American Houses (early Boston hotels), the original Tremont Temple, and the old Charlestown City Hall, all since demolished. This mansion is the only extant building by Washburn to my knowledge. The brick and sandstone building features paired columns at the entrance with Egyptian Revival lotus leaf capitals, additionally, the triangular dormers at the mansard roof provide a slight Egyptian Revival note. The Egyptian Revival style was rarely used in American domestic architectural design. More frequently used in the design of cemetery entrance gates and memorials in the form of obelisks, the Egyptian Revival made sporadic appearances in the design of American buildings between the 1820s and the 1870s. Another period of the Egyptian Revival architectural style also occurred in the 1920s, with design of silent movie theaters, which coincided with the discovery of King Tut’s tomb in Egypt.
