Appomattox Court House National Historical Park preserves the nineteenth century Virginia village of Appomattox Court House, including the McLean House where Confederate General Robert E. Lee surrendered the Army of Northern Virginia to Union General Ulysses S. Grant on the 9th of April 1865.
Lee signed the surrender terms on the 9th of April 1865, and the Army of Northern Virginia laid down its arms and marched away on the 12th of April 1865.
The village began as a stagecoach stop called Clover Hill along the Richmond to Lynchburg road, and it became the Appomattox County seat after the county was created by an Act on the 8th of February 1845.
The village kept declining after the war, and in 1892 a fire destroyed the courthouse and its records, prompting officials to move the county seat to the railroad settlement that became the town of Appomattox.
The War Department's holdings at the site were transferred to the National Park Service in 1933, and the park was listed on the National Register of Historic Places on the 15th of October 1966.
The roughly 1700 acre park includes original structures such as the Clover Hill Tavern, reconstructed buildings including the McLean House, a driving tour, hiking trails, the site of Lee's headquarters, and an artillery park with cannons.
