The Capitol Stones

If you live in Washington long enough, someone will tell you a ridiculous-sounding story about a secret place in Rock Creek Park where there are huge piles of historic stone torn off the Capitol and abandoned. The Capitol Stones are an urban legend, but a legend that's absolutely true.

During a 1958 renovation of the Capitol, the Architect of the Capitol removed hundreds of sandstone and marble blocks from the building, some featureless slabs and some ornate carved pieces, most dating from the building's original construction. Not quite sure where to put this historic stone (the law barred selling or disposing of it), the builders quietly piled the stones behind a maintenance shed in Rock Creek Park, and abandoned them.

And there they remain.

The stones, now mossy and in deep woods, feel more like an ancient architectural ruin than a dump site. The piles, some 20 feet tall, form almost orderly rows. Every few feet you'll see something unusual—a cornice poking out, a builder's mark, a striking stone carving. 

The abandoned stones are an entirely unofficial monument. According to a 2015 story in Washingtonian magazine, neither the Architect of the Capitol nor the National Park Service maintains the site. The government neither discourages nor encourages visitors. The path to the stones is unmarked, but well maintained. If you do go, be careful walking around, and be gentle on the stones. 

Updated as of June 2022: There is a chain-link fence around the stones with "do not enter" signs. However, you can still view the stones through the fence.

Updated as of August 2022: The DCist reported the National Park Service will begin removing the stones from Rock Creek Park.
