Gungywamp is a 100-acre area in Groton that archaeologists consider a treasure. Its exact origins remain a mystery, but its unusual stonework and artifacts span centuries, if not eons.
Among Gungywamp's features are stone chambers that researchers believe were Colonial-era root cellars or animal birthing shelters erected by English-Scottish immigrants. Of these, two are intact. One contains a solar calendar: during the spring and autumn equinox, the sun shines through an opening in the west wall and lights the opposite wall, which reflects some light into a smaller, interior, beehive-shaped chamber. Solar timetables helped farmers decide when to plant and harvest crops or avoid crop freeze in the winter and crop rot in the summer. Archaeologists have found no evidence to support the popular theory that medieval Celtic monks built the chambers. Still, the lack of artifacts in the chambers leaves room for speculation.
I can sleep better at night knowing such a thing as a Gungywamp exists.
