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". 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. It is a slick developer's model dropped into an urban renewal slot in Anycity, U.S.A.—a textbook example of urban character assassination." Architect Donlyn Lyndon called it "an energetically ugly, square shaft that offends the Boston skyline more than any other structure". In 1990, Boston Globe architecture critic Robert Campbell commented: "The Prudential Center has been the symbol of bad design in Boston for so long that we'd probably miss it if it disappeared." Ownership The Prudential Center is currently owned by Boston Properties. The building is one of several Prudential Centers built around the United States (such as the tower in Chicago) constructed as capital investments by Prudential Financial (formerly, The Prudential Insurance Company of America). Preceding Prudential Financial's demutualization, Prudential sold many of its real estate assets, for instance most of the air rights in Times Square, and the Prudential Center in Boston, to put cash on the corporate balance sheets. 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. Boston-based law firm Ropes & Gray moved into much of this space, including the 37th through 49th, in fall 2010. Other major tenants include Wall Street investment firm Home State Corporation, Partners HealthCare, Club Monaco, Exeter Group and Accenture. Boston Properties acquired the building in 1998.

Using similar negotiations, Prudential retains two notable signs in Times Square.
