Ropewalk (Building 58)
The Ropewalk is a granite structure which extends nearly a full block inside the fence on Chelsea Street. In this quarter-mile long space, ropes for the Navy in World War II were spun. Today the building is slated to be redeveloped for 90 apartments and a small museum. The BRA has designated Frontier Enterprises, Inc. to develop the building; expected occupancy of some units is in spring 2017.
