This granite quarry was first used in the early 1900’s and produced granite for the Williamsburg Bridge in New York, the Manhatten Bridge, the New York County Courthouse, the Boston Museum of Fine Arts and the JFK Memorial in Arlington National Cemetery. It once was a major industrial site employing hundreds of men and was a forest of stacks, masts, booms and derricks. The Quarry is now a part of the Island Heritage Trust and is an excellent place to explore and hike. The Grout Pile Trail and Glacial Erratic Trail guide you around the quarry and through the woods where you can view a panorama of Webb Cove, Merchants Row, Isle Au Haut and the Camden Hills.
