NPR has been comfortably ensconced in its new headquarters at 1111 North Capitol Street NE for some time now. But what of the public radio network’s old digs at 635 Massachusetts Avenue NW in Mount Vernon Square?

Last month, we posted a photograph taken part of the way through the building’s razing, as the developer that owns the site, Boston Properties, clears it out to make way for yet another gleaming, glassy office building.

But now, the old NPR building is all gone. Via YouTube comes the tumbling down of the last side of the former radio headquarter’s carcass.
