In recent years the Amoskeag Millyard and its residential historic district have experienced continual redevelopment. Many properties originally built in the nineteenth century as tenement housing for mill workers have been retro-fitted to create stylish and eclectic residential condominiums, retail stores, and restaurants. The Pandora Mill is one such converted mill building, situated between the Merrimack and a large cluster of new developments. Elm Street, a block to the east, is the commercial center of the city and northern New England.
