Washington Monument State Park is a public recreation area located approximately one mile (1.6 km) southeast of Boonsboro, Maryland.

The dry-laid stone tower was built on July 4, 1827, by the citizens of Boonsboro who marched to the site en masse after assembling in the town square at 7 a.m. At the end of that day, the tower stood at 15 feet (4.6 m) high on a base 54 feet (16 m) in circumference.

Later that year, "after the busy season", workmen returned to complete the tower to a height of 30 feet (9.1 m).

[7] Although it was a popular meeting place for the citizenry of Boonsboro, weather and vandalism reduced the monument to rubble.

[6] The park offers access to the Appalachian Trail,[9] picnicking facilities,[4] and a museum with exhibits on the natural and cultural history of the area.
