The Pow-Wow Oak was an historic tree located in the Belvidere neighborhood of Lowell, Massachusetts. This 300-year-old tree is believed to have served as a gathering place for pow wows held by the Native American Wamesit tribe. The Wamesit Indians congregated in this area for thousands of years, and the land on which this tree grew on was held as sacred to them as was the tree itself. It is also said that Revolutionary War soldiers such as Deacon Thomas Clark, Captain John Trull, and General Joseph Varnum, as well as others from this New England hamlet, traveled past the Pow-Wow Oak on their way to defend Lexington and Concord on Patriots Day, April 19, 1775. This was the very beginning of the American Revolution, which started in the Commonwealth of Massachusetts.
