There was not a lot of history to be found about this particular garrison. But, according to “History of Sudbury Massachusetts 1638-1889”, the Parmenter House was among the Garrison Houses in Sudbury used during the Indian Wars. It was one story high and had a room at each end and stood about twenty-five rods (400+ feet) northwest of the Adam Howe place. (Adam was the third proprietor of “Howe’s Tavern”, which is now Longfellow’s Wayside Inn). According to the history, when the Wayside Inn (made famous by Longfellow's poem) was built, the workmen retired to the Parmenter Garrison House at night for safety.
For a time, the building was owned and occupied by Abel Parmenter. As is tradition, garrison houses were named from their early occupants. Since Parmenter was the name of the first known occupant of this house, that is why the old building became known as the Parmenter Garrison.
This should be a park and grab for most. Please bring your own pen and re-hide as found to keep the container out of sight!
