About 17 miles south of downtown Boston, South Weymouth offers New England charm without the city price tag. Columbian Square anchors daily life with retail shops, eateries, and landmark buildings -- the Fogg Library, Fogg Opera House Building, and Old South Union Church among them. Groceries are within easy walking distance, and the neighborhood's tree-lined streets and quiet atmosphere make it easy to decompress after a long day.
The housing stock reflects classic New England sensibilities: Cape Cods, bungalows, Colonials, Victorians, and raised ranches share the streetscape with modern apartment communities. Renters will find apartment communities ranging from cozy one-bedroom units to spacious multi-bedroom homes, spanning both historic and contemporary builds.
As part of Weymouth, the second-oldest settlement in Massachusetts, South Weymouth carries deep historical roots while actively looking forward. South Shore Hospital, the area's largest employer and a regional healthcare anchor, is based here. The former Naval Air Station site is being redeveloped as Union Point, a 1,400-acre mixed-use community taking shape with residential, retail, and commercial uses.
