One of Worcester’s most iconic buildings is Mechanics Hall. It was built in 1857 to house educational and cultural activities by the Worcester County Mechanics Association. This organization was formed in 1842 to promote the mechanical arts and to provide education and training for industrial workers. Mechanics Hall featured meeting rooms, a library, and two halls. The building was designed by Elbridge Boyden, a Worcester architect. By the mid-twentieth century, other organizations had taken up the role once played by the Mechanics Association and other auditoriums had found favor with the public. To raise revenue, Mechanics Hall was rented out for sporting events and for a time was even a roller skating rink. The old building was no longer the cultural center it had once been and was in danger of demolition. Citizens rallied to save Mechanics Hall, which was restored and reopened in 1977. Today, the Mechanics Association‘s primary mission is to maintain Mechanics Hall, which is considered to be the finest pre-Civil War concert hall in the country and one of the four finest in North America. The Main Hall features the 1864 Hook Organ (aka the Worcester Organ). Built by E. & G.G. Hook, it is the oldest unaltered four-keyboard organ in the Western Hemisphere.
