The Broken Ground, named for its diverse physical features, is an area of land of approximately five square miles bounded by Oak Hill Road, the Loudon town line, I-393, and the Power Line. With its unique topography and natural features, it has remained undeveloped since Concord was first settled by Ebenezer Eastman in 1725, except for farming in the 19th century. On two occasions since 1980, large-scale developments were attempted on the easterly edge of the land. The failure of both due to poor economic conditions has allowed it to remain virtually untouched forest, other than managed timber sales. In 2013, the City Council approved the purchase of 272 acres east of the power lines between Curtisville Road and Portsmouth Street. The existing trail system was completed in 2016 by the Concord Trails Subcommittee and friends.
