Located in the Russell Corner section of Princeton, Massachusetts, this handsome brick mansion had its start as a smaller commercial building before becoming one of the grandest residences in town. In 1823, Charles Russell (1793-1882) built this square brick building to house his store, a post office, and second floor meeting hall for public gatherings and the local Masonic Lodge and local anti-slavery society. By the mid-nineteenth century, Charles Russell was a well-known figure in Boston. He was elected first as representative to the State Legislature and later as representative of the County of Worcester to the State Senate. He and his wife, Persis, had two sons, Charles Theodore Russell (1815-1896) and Thomas Hastings Russell (1820-1911), who both became prominent lawyers and politicians. In about 1874, Thomas Russell enlarged the family’s commercial block in Princeton, adding a third floor in the form of a mansard roof, a wrap-around porch, and belvedere at the roof. The old store became known as the Mansion House and served as Thomas’ summer residence outside of the city. The Mansion House has been lovingly preserved and is a lasting landmark that tells the story of Princeton from its beginnings as a rural community to an exclusive summer colony in the 19th century.
