File:8064 Church Graveyard, Zion Reformed United Church of Christ in Hagerstown, MD.jpg

Located at 201 North Potomac St., Hagerstown, MD.

Found in 1770, this stone church is the oldest within Hagerstown's town limits, and is the oldest church within Washington County that has seen continuous use since its construction. The land on which the church stands was purchased from the estate of the founder of Hagerstown, Captain Jonathan Hager, whose grave can be found in the church cemetery. Hager died on December 6, 1775, when a heavy beam being lifted to the ceiling of the church slipped and fell, crushing him.

The churchyard has become the final resting place for veterans of the French and Indian War, the American Revolution, the War of 1812, the Mexican-American War, the Civil War (1861–1865) and World War I.

The two bells hanging today in the tower were cast in 1785 in Rotterdam, Holland, in the foundry of G. Bakker. The original bell tower was not a tower but a regular church steeple. In 1871 the second bell steeple was built but in 1878 was destroyed by a tornado and rebuilt. In 1884 the present tower was erected and dedicated and in 1885 the original bells were returned to their place in the tower.

In July 1863, the citizens of Hagerstown heard the sounds of battle emanating from Gettysburg and saw Gen. Robert E. Lee's defeated Confederate army approaching from the northeast. Union troops deployed south of town, awaiting their approach. Skirmishing took place in the town itself, but Lee's troops managed to slip by and continue south towards Virginia.

Mr. Thomas F. McCardell wrote and published an account of his involvement with Gen. Custer. He told how, at the time of Gen. Lee’s withdrawal from Gettysburg, it fell to his lot, as a boy, to conduct Gen. Custer, the 24-year-old cavalry leader of the Union Army, into the tower of Zion Church, for the purpose of locating the troops of Gen. Lee, and how, while in the belfry, the bullets of sharpshooters aimed at Gen. Custer rattled against the bells of Zion Church.
