Located among in suburban Hartford, CT's office parks, strip malls and golf courses, the corporate headquarters of CIGNA are unexpectedly cool. Reason 1: A ROBOT delivers mail to each department. Reason 2: The building itself is low-lying and sleek, with green-tinted windows that, on sunny days, disappear into the sky. It was designed by Gordon Bunshaft, who also designed the stunning Beinecke Library at Yale and won the Pritzker Prize in 1988, and it's surrounded by gardens, courtyards and sculpture by landscaping badass Isamu Noguchi. A couple of years ago, CIGNA considered tearing the building down and selling the land to a golf course developer, but architectural preservationists intervened. CIGNA staffmembers often joked about this, the subtext being, "Can you believe that anyone would want to preserve this?" [A NYT article from 2001 details the debate]UPDATE: The Hartford Courant recently published a grateful editorial about CIGNA's decision to preserve the Bunshaft building.
