Mechanics Hall was a building and community institution on Huntington Avenue at West Newton Street from 1881 to 1959. Commissioned by the Massachusetts Charitable Mechanic Association, it was designed by William Gibbons Preston and located between the Boston and Albany railroad yards and Huntington Avenue. It was razed for the Prudential Center urban renewal project of the early 1960s. The site is on the north side of Huntington Avenue, and since 1941 has been served by Prudential Station of the MBTA Green Line E branch.
