Thanks to Rick for letting us know:
“Joan of Arc is swordless again at Meridian Hill Park. Any ideas when and what happened?”
The iconic Jeanne d’arc statue was completely restored in 2011.
[Ed. Note: Check out a video of the original dedication with President Harding in 1922 here.]
Maybe someone can figure out how to do this again in the meantime:
