Alvan Clark & Sons was an American maker of optics that became famous for crafting lenses for some of the largest refracting telescopes of the 19th and early 20th centuries. Founded in 1846 in Cambridgeport, Massachusetts, by Alvan Clark (1804–1887, a descendant of Cape Cod whalers who started as a portrait painter), and his sons George Bassett Clark (1827–1891) and Alvan Graham Clark (1832–1897). Five times, the firm built the largest refracting telescopes in the world. The Clark firm gained "worldwide fame and distribution", wrote one author on astronomy in 1899. The 18.5-inch (470 mm) Dearborn telescope (housed successively at the University of Chicago, Northwestern University and Adler Planetarium) was commissioned in 1856 by the University of Mississippi. The outbreak of the Civil War prevented them from ever taking ownership. As a result, it was being tested in Cambridgeport when Alvan Graham observed Sirius B in 1862. In 1873 they built the 26-inch (660 mm) objective lens for the refractor at the United States Naval Observatory. In 1883, they build the 30-inch (760 mm) telescope for the Pulkovo Observatory in Russia, the 36-inch (910 mm) objective for the refractor at Lick Observatory was made in 1887, and the 40-inch (1,000 mm) lens for the Yerkes Observatory refractor, in 1897, only ever exceeded in size by the lens made for Great Paris Exhibition Telescope of 1900. The company also built a number of smaller instruments, which are still highly prized among collectors and amateur astronomers. The company's assets were acquired by the Sprague-Hathaway Manufacturing Company in 1933, but continued to operate under the Clark name. In 1936, Sprague-Hathaway moved the Clark shop to a new location in West Somerville, Massachusetts, where manufacturing continued in association with the Perkin-Elmer Corporation, another maker of precision instruments. Most of Clark's equipment was disposed of as scrap during World War II, and Sprague-Hathaway itself was liquidated in 1958. Alvan Clark & Sons Telescopes

The Hastings Square Historic District is a historic district that encompasses Hastings Square, a small city park in Cambridge, Massachusetts, and the residential properties that abut it.

The Grand Junction Railroad Bridge is a steel plate girder bridge carrying the Grand Junction Railroad over the Charles River in Boston, connecting the Boston University campus to Cambridgeport. In September 2009, the Commonwealth of Massachusetts finalized an agreement to purchase several CSX rail lines in eastern Massachusetts, including the Grand Junction tracks from the Beacon Park Yard in Allston, through Cambridge. The deal was closed on June 17, 2010.

The Boston University Bridge, originally the Cottage Farm Bridge and commonly referred to as the BU Bridge, is a steel truss through arch bridge with a suspended deck carrying Route 2 over the Charles River, connecting the Boston University campus to Cambridge, Massachusetts. The bridge, with the Grand Junction Railroad Bridge directly underneath it, is incorrectly rumored to be the only place in the world where a boat can sail under a train driving under a car driving under an airplane. Other such places include the Steel Bridge in Portland, Oregon, the Manhattan Bridge in New York City and the 25 de Abril Bridge in Lisbon, although all of those bridges feature road and rail on the same span. In this case the rail and road traffic are on separate bridges.

Magazine Beach is an American riverside park in Cambridge, Massachusetts. It is located on the left bank of the Charles River, across Memorial Drive from Cambridgeport, and opposite Agganis Arena and other Boston University facilities on the far bank. Magazine Beach is Cambridge's second largest park, being about 15 acres (6.1 ha) stretching along the river from Pleasant Street to the BU Bridge. The park includes a free outdoor swimming pool (Veteran's Memorial Pool) as well as ball fields, exercise equipment, picnic areas, and other typical urban park features. The Paul Dudley White Bike Path runs through the park. The park's namesake, a gunpowder magazine from 1818, is in the park. It is the oldest building in the Charles River Reservation. There was a swimming beach at the park in the early and mid 20th century, attracting about 60,000 swimmers in a season, but swimming in the Charles River became dangerous due to pollution, and was forbidden in 1949.

Kerry Quarter in Cambridge, Massachusetts, United States also called the Lower Marsh, was reclaimed from the Charles River during the construction of the Harvard River Dormitories. In a deal with the city of Cambridge, Harvard sold much of the reclaimed land along Putnam Ave to parishioners of St. Paul's Church in nearby Harvard Square. The new immigrants that moved to the area were almost entirely of Irish descent, and many hailed from County Kerry one of the hardest hit in the Irish Famine thus giving the area its name. For a long time this small quarter near Harvard housed some of the poorest people in the city, and still has several low income housing developments in around Putnam Ave. Although now mostly gentrified with condos taking over the former triple deckers of Irish immigrants, old residents still refer to it as the Kerry Quarter.

Boston University Academy (BUA) is a private high school operated by Boston University. Founded in 1993 and located on the Boston University campus, the academy is geared toward college preparatory work. As part of its integration with the university, students are able to take college courses for credit their junior and senior years, and are guaranteed acceptance to Boston University upon maintaining a 3.0 grade point average in Boston University courses. BUA's student body is drawn from 55 communities: 52% come from public schools, 39% from independent schools, 7% from parochial schools and 2% are from home-school or international schools; 57% are students of color and 47% of students come from multilingual households (representing 26 languages). BUA provides need-based tuition assistance to approximately 31% of the students as of the 2019–2020 academic year.

The George Sherman Union (GSU) is the student union building at Boston University and Boston University Academy. The Brutalist-styled building opened in Spring 1963. When it opened, the Union had a 10-lane bowling alley in its basement. The building is named for the Boston industrialist, philanthropist, and Boston University benefactor. The Union was modeled after similar student centers in Midwestern universities. Inside are many of Boston University's administrative offices, a nine-restaurant food court, two bank branches, several auditoriums and other open space, as well as the BU Scarlet Safewalk service. The GSU abuts Mugar Memorial Library, the school's main library. Students come to the GSU to organize events, gather and exchange information, and meet people. It provides an atmosphere for study and conversation. As the community center of Boston University, it provides cultural, social, and recreational programs that supplement regular classroom education. The facilities of the George Sherman Union are reserved for the exclusive use of students, faculty, staff, and alumni of Boston University. The GSU was one of many buildings benefitting from renovations during the summer of 2010. The Union Hall food court and study lounges were later renovated again, completing in August 2020. The East Campus Boiler Plant, which heats and cools the GSU was converted from oil to natural gas, reducing the University's carbon footprint by 3%. More wireless access points were added, as well as compost and recycling receptacles to encourage the university's dedication to become more green.

The Mugar Memorial Library is the primary library for study, teaching, and research in the humanities and social sciences for Boston University. It was opened in 1966. Stephen P. Mugar, an Armenian immigrant who was successful in the grocery business, provided the naming gift to commemorate his parents. Mugar's entrance carries an inscription from Stephen honoring his parents. In coming to America from Armenia my parents opened the door of Freedom to me. America's public schools & libraries opened my eyes to the unlimited opportunity in this great land, as well as the privileges and obligations of citizenship. May this library serve over the years as a similar inspiration to all who use it. In memory of my father and mother Sarkis and Vosgitel Mugar. By their grateful son – Stephen P. Mugar –
