The Chilton Club is a private social club established in 1910, in the Back Bay area of Boston, Massachusetts. Founded by Pauline Revere Thayer, the club was intended in part as a counterpoint to the Mayflower Club. The club was named after Mary Chilton because she had been the first woman to step out of the Mayflower. The club occupies a large red brick building on Commonwealth Avenue, designed in 1870 by architect "Henry Richards of the firm of Ware and Van Brunt." (However, some claim the building was designed by architects Peabody and Stearns.) The building has been altered and expanded over the years."On May 18, 1910, the Chilton Club applied for (and subsequently received) permission to significantly remodel and expand the house, including removing the original third floor, with its mansard roof, and adding three additional floors, two of brick and the third "in roof." They also received permission to construct an addition at the rear, 38 feet by 18 feet 9 inches, five stories high above the basement, four of brick and one "in roof." The Club retained the firm of Richardson, Barott, and Richardson, and the work was overseen by F. L. W. Richardson, son of the noted architect Henry Hobson Richardson. The addition was completed in February 1911. ... On May 28, 1926, the Club acquired 150 Commonwealth, which had remained in the Baker Estate until the previous year. They remodeled the house, combining it with 152 Commonwealth." Some early members included:

The Hotel Vendome Fire Memorial commemorates victims of the Hotel Vendome fire. It is installed along Boston's Commonwealth Avenue Mall, in the U.S. state of Massachusetts. The work was designed by the artist Ted Clausen and landscape architect Peter White. A group of firefighters originally proposed the memorial in 1982, but it was not initially approved by the Boston Arts Commission. The rejected proposal led to claims that the affluent residents of Back Bay had thwarted the proposal out of snobbery, regarding the design as "tacky." The Boston Globe columnist Mike Barnicle attributed the obstruction to the "elitism and self-importance" of those in the neighborhood. The design was finally approved in 1995 and ground was broken the following year.

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 (especially Newbury and Boylston Streets, and the adjacent Prudential Center and Copley Place malls) and home to several major hotels.The Neighborhood Association of the Back Bay considers the neighborhood's bounds to be "Charles River on the North; Arlington Street to Park Square on the East; Columbus Avenue to the New York New Haven and Hartford right-of-way (South of Stuart Street and Copley Place), Huntington Avenue, Dalton Street, and the Massachusetts Turnpike on the South; Charlesgate East on the West."

The Boston Marathon bombing was a domestic terrorist attack that took place during the annual Boston Marathon on April 15, 2013. Two terrorists, the brothers Dzhokhar Tsarnaev and Tamerlan Tsarnaev, planted two homemade pressure cooker bombs, which detonated 14 seconds and 210 yards (190 m) apart at 2:49 p.m., near the finish line of the race, killing three people and injuring hundreds of others, including 17 who lost limbs.Three days later, April 18, 2013, the Federal Bureau of Investigation (FBI) released images of two suspects. They were later identified as the Tsarnaev brothers, who were Chechen Kyrgyzstani-Americans. Following their identification, at 10:35 p.m., they killed a MIT policeman. At 11:00 p.m. they kidnapped a man in his car. At 12:15 a.m., April 19, the man escaped. At 12:45 a.m. they had a shootout with the police in nearby Watertown, during which two officers were severely injured (one of whom, DJ Simmonds, died a year later). Tamerlan was shot several times, and his brother Dzhokhar ran him over while escaping in the stolen car. Tamerlan died soon after. An unprecedented manhunt for Dzhokhar ensued with thousands of law enforcement officers searching a 20-block area of Watertown. Residents of Watertown and surrounding communities were asked to stay indoors, and the transportation system and most businesses and public places closed. Around 6:00 p.m., a Watertown resident discovered Dzhokhar hiding in a boat in his backyard. Dzhokhar was shot and wounded by police before being taken into custody.During questioning, Dzhokhar said that he and his brother were motivated by the wars in Iraq and Afghanistan, that they were self-radicalized and unconnected to any outside terrorist groups, and that he was following his brother's lead. He said they learned to build explosive devices from the online magazine of Al-Qaeda in the Arabian Peninsula. He also said they had intended to travel to New York City to bomb Times Square. On April 8, 2015, he was convicted of 30 charges, including use of a weapon of mass destruction and malicious destruction of property resulting in death. Two months later, he was sentenced to death, though in July 2020, this sentence was vacated by the United States Court of Appeals for the First Circuit. On March 22, 2021, a writ of certiorari was granted by the Supreme Court of the United States, which considered the questions of whether the lower court erred in vacating the death sentence. The Supreme Court heard arguments on October 13, 2021, as United States v. Tsarnaev; on March 4, 2022, the Court upheld the death penalty, reversing the First Circuit Court's decision.
