The Bourne Stone is a large slab of pink granite that measures about 4 feet long and 2 feet wide and weighs about 300 pounds. That's about all that anyone can agree on. Like many ancient artifacts found in southeastern Massachusetts, its history melds together native American and colonial cultures. There are markings on the granite that some experts believe are important messages. Other experts believe that these are nothing more than scrapes caused by the weather.
Recent interest in Viking and Templar voyages has lead to speculation that it is a runestone and could be part of a larger web of information. It is called the Bourne Stone because it was first seen in the small New England village of Bourne, Massachusetts. The Bourne Historical Society now houses the Bourne Stone at its headquarters within the Jonathan Bourne Historical Center. It is open to the public and anyone can visit to see this ancient artifact.
