The town of Boonsboro, Maryland lies nestled at the foot of South Mountain in Washington County. The land where the town is located was part of two tracts, "Beale's Chance" and "Fellowship", owned by two brothers, George and William Boone. Founded in 1792, when the brothers laid out the land in half-acre lots. Originally named Margaretsville in honor of George's wife, it was eventually changed to Boonesborough and then later to its shortened spelling – Boonsboro.

With the construction of the National Road, a turnpike connecting Baltimore to the west, Boonsboro grew and prospered. In 1823, a new process called "macadam" was used to finish an unpaved section of the turnpike from Boonsboro to Hagerstown. This was the first time the road building process was used in the United States.

On the 4th of July in 1827, the citizens of Boonsboro erected in one day the first monument to honor George Washington on top of South Mountain. Used during the Civil War, the monument was restored in 1882 and again in 1936 by the Civilian Conservation Corps.

The first battle of the Civil War fought on northern soil, was the Battle of South Mountain September 14, 1862. Churches, public buildings and homes in the town were used as hospitals.

Today, Boonsboro is a quiet bedroom community catching the over-flow growth of Frederick County, as commuters to the Baltimore-Washington D.C. area move westward in search of homes with a rural setting.
