The New England Masonic Charitable Institute building is located in Center Effingham, New Hampshire, and is among the rural town’s most impressive structures. The structure was built in 1858 by the Charter Oak Lodge No. 58 of Free and Accepted Masons as a school to educate orphans of Masonic members, but they also admitted local students. It is the only known school building purposely constructed by Masons in the United States. Classes were conducted from 1861 to roughly 1882 with students boarding with local families. The impressive Italianate style building is dominated by a six-story bell tower supporting an octagonal cupola, and exhibits many architectural details including the corner quoins, paired eave brackets, and dentilled cornice. Charter Oak Lodge No. 58 sold the building to the Town of Effingham in 1891 for one dollar but retained rights to the second floor temple room in perpetuity. The walls and ceilings of the Lodge’s temple space are covered with trompe l’oeil murals attributed to Massachusetts painter Philip A. Butler. Images of classic sculptures, architectural details and Masonic symbols, including the All-Seeing Eye, are incorporated into the paintings. Heavily water-damaged in the late 1980s, they have since been restored. The building remains occupied by the Effingham Public Library, what a library building for a town of just 1,700 residents!
