Located on a green in the center of Wayland is the Mellen Law Office. It was built in 1826 by Samuel Hale Mann, who only practiced law there for four years before ill health forced him to sell it (and his house across the street) to Edward Mellen, who eventually became chief justice of the Court of Common Pleas in Worcester. The office housed many other offices and businesses over the years, all the while remaining in the possession of the Mellen family. In 1971, it was donated to the town and is maintained by the Wayland Historical Society.
