YARMOUTH — The Yarmouth Historical Society will break ground for the new Yarmouth History Center at 11 a.m. tomorrow.

The society has hired TPD Construction of Sanford to convert and expand the former Yarmouth Water District headquarters at 118 East Elm St.

Located beside the Royal River, the center will feature a gallery, office space, archives room and gathering space for educational programs.

The $1 million project was made possible by substantial gifts from Leon Gorman of Yarmouth and Jim Gorman of Cumberland. Their mother, the late Barbara Bean Gorman, daughter of L.L. Bean’s founder, helped to start the society.

The center is scheduled to be completed by November.
