The Beaman Oak was the largest white oak tree in the Commonwealth of Massachusetts. It stood in the front yard of a colonial era three-story house in the town of Lancaster. It was so named because Gamaliel Beaman had originally settled the spot in 1659. The oak became known as a prominent landmark in Central Massachusetts and is featured prominently on the town seal of West Boylston.
In 1970, the Beaman Oak's circumference at its base was 31feet, with a circumference 5feet above the base of 31feet, and its height was 75feet and spread was 75feet.
The oak's trunk was partially hollow towards the end of its life. After a storm severely damaged it, the tree was cut down in 1989.[1]
