The Green Line is a light rail system run by the Massachusetts Bay Transportation Authority (MBTA) in the Boston, Massachusetts, metropolitan area. It is the oldest Boston rapid transit line, and with tunnel sections dating from 1897, the oldest subway in North America. It runs underground through downtown Boston, and on the surface into inner suburbs via four branches on several radial boulevards. With an average daily weekday ridership of 137,700 in 2019, it is the third most heavily used light rail system in the country. The line was assigned the green color in 1967 during a systemwide rebranding because several branches pass through sections of the Emerald Necklace of Boston.
Back Bay is an officially recognized neighborhood of Boston, Massachusetts, built on reclaimed land in the Charles River basin. Construction began in 1859, as the demand for luxury housing exceeded the availability in the city at the time, and the area was fully built by around 1900. It is most famous for its rows of Victorian brownstone homes—considered one of the best preserved examples of 19th-century urban design in the United States—as well as numerous architecturally significant individual buildings, and cultural institutions such as the Boston Public Library, and Boston Architectural College. Initially conceived as a residential-only area, commercial buildings were permitted from around 1890, and Back Bay now features many office buildings, including the John Hancock Tower, Boston's tallest skyscraper. It is also considered a fashionable shopping destination and home to several major hotels.

The Veterans of Foreign Wars Parkway is a historic parkway in Boston, Massachusetts. The southern terminus of the parkway is at Washington Street at the Dedham-West Roxbury border, from where it travels north and then east, ending at a junction with Centre Street, near the Arnold Arboretum.

Most of its length, from Spring Street in West Roxbury to its eastern end, is administered by the Massachusetts Department of Conservation and Recreation (DCR), a successor to the Metropolitan District Commission (MDC) which oversaw the road's construction. The parkway was built in stages between 1930 and 1942, and was designed to provide a parkway connection from the Upper Charles River Reservation to other MDC parks via the West Roxbury Parkway. The DCR portion of the road was listed on the National Register of Historic Places in 2005. The road formerly carried the designation for U.S. Route 1.
