At its Industrial Era prime, Lowell was a manufacturing powerhouse that employed more than 10,000 workers and used innovative technology to mass-produce cotton cloth. By the 1970s, it was just another failing mill town, an economically depressed community synonymous with drugs and crime. Today, Lowell is vibrant again. By embracing historic preservation, nurturing the arts, and aggressively promoting tourism, the city has revitalized itself. It offers riverboat canal cruises, gives walking tours of its Cambodian neighborhoods, and has converted former mill buildings into offices and condos. The legendary Boott Cotton Mills, for example, now houses lofts with striking views of the Merrimack River. And Lowell isn't only for history buffs. It's rich in arts and culture, with more than a half-dozen museums, several performance centers, and a repertory theater. Jocks are welcome, too; Lowell also sports the Devils (an American Hockey League franchise formerly called the Lock Monsters) and the Spinners (a minor-league affiliate of the Red Sox) . Classy restaurants, funky cafes, and art galleries round out the city's profile.
