Assembly Square is a neighborhood in Somerville, Massachusetts. It is located along the west bank of the Mystic River, bordered by Ten Hills and Massachusetts Route 28 to the north and the Charlestown neighborhood of Boston to the south. The district's western border runs along Interstate 93. Located 2.5 miles (4.0 km) from downtown Boston, the 143 acres (580,000 m2) parcel is named for a former Ford Motor Company plant that closed in 1958. The area is home to Assembly Row, a 45-acre (180,000 m2) mixed-use, smart growth development that broke ground in April 2012. It includes premium retail outlets, restaurants, residential space, state-of-the-art office and research and development space, a 12-screen cinema and a 200-room hotel. Other amenities include a marina, revitalized waterfront park, bike paths and other green space. Assembly Row's first stage of development was the Assembly Square Marketplace. Completed in 2006, the marketplace is a "power center" that comprises retail stores Christmas Tree Shops, Burlington, Trader Joe's, Staples, TJMaxx, and Bed Bath & Beyond. The area is served by the MBTA Orange Line at Assembly station.
