Stone chambers, like the one pictured below, are scattered throughout New York’s Hudson Valley. They’ve been around a long time, 1,000 years+, and nobody knows who built them or why. From Druid temples, caves of the devil, and paranormal/UFO portals to Native American sweat lodges and Colonial root cellars, stories and theories abound. One thing is certain: the eternal quality of stone as an artistic and architectural medium.
