Pittsfield is the center of Berkshire County, Massachusetts. For centuries, visitors have traveled trails, railroads, and highways across the Berkshire Hills of western Massachusetts to enjoy the serene beauty of Pontoosuc and Onota Lakes, shop on bustling North Street, or stay at a fine hotel. Many more moved here from across the country and around the world to work at Pittsfield's farms and factories. Since the early 19th century, Pittsfield has been host to woolen mills and General Electric's factories, hotels and motels, hospitals and schools, and much more. Cultural sites, such as Arrowhead, where Herman Melville wrote Moby-Dick, and Park Square, the location of the first agricultural fair ever held in the United States, continue to attract visitors to the city.
