Assembly Square Marketplace is a power center and mixed-use development located in the Assembly Square neighborhood of Somerville, Massachusetts. From the 1980s until the mid-2000s, it was an enclosed shopping mall called Assembly Square Mall. Scheduled plans for the facility call for a six phased expansion, thus changing its classification into super regional mall. 66.5 acres (269,000 m2) of office, retail, residential, research and development, hospitality and entertainment space are envisioned by project completion in 2011.
Assembly Square Mall opened in 1980. The mall building was previously occupied by Somerville Assembly, a Ford Motor Company factory, and was later used as a supermarket distribution center before its conversion to a mall.
The 322,000-square-foot (29,900 m2) mall was originally anchored by a 79,000 sq ft (7,300 m2). Jordan Marsh and a 95,637 sq ft (8,885.0 m2). Kmart; these anchor stores remained the same until 1996, when Macy's acquired Jordan Marsh. Macy's closed the store in 1997, and by 1999, it was replaced with Building 19.
