Christian Scientists have won their long, twilight struggle against brutalism -- so says a wrecking ball at the corner of 16th and I streets in Washington, D.C.

Churchgoers never liked their 1971 classic brutalist structure -- an architectural style that is well, brutal -- and have even suggested it has something to do with their dwindling numbers.
