A newly formed nonprofit has acquired the historic Poplar Grove Estate and Tide Mill in Mathews County. The Poplar Grove and Tide Mill Foundation plans to restore the pre-Revolutionary War site and open it for public education. The property once milled corn for George Washington’s troops and later belonged to John Lennon and Yoko Ono. Restoration efforts will preserve one of the last remaining tide mills in the U.S., with hopes of adding interactive displays to showcase its history.
