“Dear PoPville,
I was wondering if any readers have some information about the “house” on the hill above the Dalecarlia Reservoir/Washington Aqueduct. It’s tucked behind Sibley hospital all by itself on a steep hill overlooking MacArthur Blvd and the reservoir. While built to resemble a home, I’m guessing it’s purpose had to do with the reservoir.
A small sign tacked to the front with a National Park Service emblem reads– “area closed historic preservation work in progress”. However, it clearly hasn’t been touched in years and there’s some lovely Pepe the frog graffiti to complete the dilapidated ambiance.”
