After decades without a monumental DC headquarters, the ATF headquarters building at 99 New York Avenue opened at last in 2008. It was designed by the firm of famed architect Moshe Safdie (I am told he designed Habitat67) at what is affectionately known as “Dave Thomas Circle” because of the Wendy’s prominently located in the traffic around the intersections of New York Ave., Florida Ave., and 1st Street. The result is a beautiful fortress. One story says the building’s design was modified to address new security concerns in the wake of the 1995 Oklahoma City bombings. At least one person I’ve talked to says this version is overstated, but it’s hard deny the symbolism.
