The Prudential, John Hancock and now the Four Seasons Hotel & Private Residences towers dominate the Back Bay skyline.

The New York Times called it "the showcase of the New Boston [representing] the agony and the ecstasy of a city striving to rise above the sordidness of its recent past".

[6] But Ada Louise Huxtable called it "a flashy 52-story glass and aluminum tower ... part of an over-scaled megalomaniac group shockingly unrelated to the city's size, standards, or style.

"[7] Architect Donlyn Lyndon called it "an energetically ugly, square shaft that offends the Boston skyline more than any other structure".

The Gillette Company, now a unit of Procter & Gamble, once occupied 40 percent of the space in the structure but has since vacated many of these floors.

Other major tenants include Wall Street investment firm Home State Corporation, Partners HealthCare, Club Monaco, Exeter Group and Accenture.

The building's windows have been illuminated with "GO B's" to support the Boston Bruins during the Stanley Cup playoffs and "GO SOX" or a "1" during important World Series and postseason games.

[14] Over the past few years, the Prudential Tower has been illuminated through light-emitting diodes (LEDs), that have the capacity to create a glow near the top of the building.

The lighting is used for special occasions and charitable events and can support nearly every color, including pink, maroon, red, orange, yellow, gold, green, blue, and purple.

[18] By the fall of 2007, another major development was completed along Boylston Street at the Prudential Center complex: the Mandarin Oriental, Boston hotel.

Back Bay is a stop on the Orange Line and is accessible to the complex via the Copley Place mall, to which it is attached by a walkway over Huntington Avenue.

The Prudential Center serves as one of three starting locales for the Boston Duck Tours, a popular tourist attraction in the city.

The upper master antenna, manufactured by Electronics Research, Inc. (ERI), serves WZLX 100.7, WWBX 104.1, WMJX 106.7, and WXKS-FM 107.9.
