 A precursor to later megastructure and now more integrated mixed-use complexes, its construction was heralded as the future of urban design.But, considering recent trends that emphasize more traditional streetscapes, this self-contained urban environment seems outdated.It shares its design "brotherhood" of multiple-style buildings connected by large, above-grade pedestrian spaces with two similar but much larger renewal projects, Charles Center in downtown Baltimore, Maryland, and the Prudential Center complex in Boston, Massachusetts, although these two developments have been significantly altered and have also experienced varying degrees of economic and planning success.
