In conversation, some things are better left unsaid – and in the Historic District, some things are better left unbuilt.
That’s the unspoken commentary behind a new exhibit that opened at the National Building Museum this past weekend. “Unbuilt Washington” explores the monuments and buildings – and occasional Venetian-style canal – that might have graced the District, if only they had made it past the drawing board.
There’s the colossal pyramid honoring Abraham Lincoln, or the medieval-style Memorial Bridge dedicated to Ulysses S. Grant, or the new executive mansion built further up 16th Street, atop Meridian Hill.

As a D.C. guide, I thought this exhibit was a pretty fascinating tour of an alternate Washington. And with Thanksgiving approaching, I was also left feeling grateful that some of these outlandish structures were left unbuilt – either through lack of funds, shifting priorities, or public outcry.
The exhibit reminds you that from its inception, the federal capital has presented a veritable blank slate for architectural imaginations and often competing notions of national expression.
