There used to be a brutalist Christian Science church about three blocks from the White House. Despite preservationist complaints and perhaps lawsuits, it came down some years ago, to be replaced with a glass box office building that houses a church and reading room, plus office space. It might have brought in a fair bit of revenue before the pandemic. Need I say that it has its own Wikipedia page? See <a href="https://en.wikipedia.org/wiki/Third_Church_of_Christ,_Scientist_(Washington,_D.C" rel="nofollow">https://en.wikipedia.org/wiki/Third_Church_of_Christ,_Scient...</a>.) .<p>I can't offhand think of any operating brutalist church facilities in Washington--not that I spend much time looking for them.
