The Mitchell garrison was an important building in what was, at the time, North Yarmouth, Province of Massachusetts Bay.

[1] Built in 1728, on the town's lot number 91,[2][3] it stood at the rear of today's Holy Cross Cemetery on a bluff around 50 feet (15 m) immediately above the Royal River.

The dirt path that looks like it leads to the water is actually the town's original stage road, formerly lined with elm trees.

As North Yarmouth's stagecoach travel increased in popularity, the stockade was removed and the home was enlarged to accommodate overnight guests.

[4] The home's first owner was Jacob Mitchell (c. 1672–1744), a dean and a founder of the nearby Meetinghouse under the Ledge, which stood between 1729 and 1836.
