Built in 1827, it was the first monument to George Washington to be completed. The Baltimore Washington Monument was completed two years later, although it had been started considerably earlier in 1815. The famous Washington Monument in the District of Columbia was not completed until 1885. The stone tower was built and dedicated to the first president by the citizens of Boonsboro, Maryland on July 4, 1827. The tower is 34 feet (10.4 m) tall and was built by the citizens of the village of Boonsboro. During the Civil War (1862-1865) the monument was used by the Union Army as a signal station. The citizens of Boonsboro also utilized the Monument and surrounding land as a popular meeting place, but over the years, weather and vandalism reduced it to a pile of rubble. In 1882, the restoration of the monument was undertaken and carried out under the sponsorship of the Odd Fellows Lodge of Boonsboro. At this time a canopy was added, and a roadway for vehicles was built up the mountainside to the site. A decade later the rugged tower was marred by the development of a crack in the wall. Because it was not repaired, the monument again fell in ruins. In 1920, the 1-acre (4,000 m2) site was purchased by the Washington County Historical Society, and in 1934 it was deeded to the State of Maryland for use as a State Park. The tower was rebuilt in its present form by members of the Civilian Conservation Corps, who set in place the original cornerstone and a facsimile of the dedication tablet. The Appalachian Trail goes through the state park, and passes the base of the monument. The monument was added to the National Register of Historic Places on November 3, 1972.
Pen Mar is an unincorporated community in Washington County, Maryland, and Franklin County, Pennsylvania, United States. It is one of the border towns in the United States with a portmanteau name. Pen Mar came to prominence in the 20th century due to the construction of Pen Mar Park by the Western Maryland Railroad. The construction of the Pen Mar resort caused the area to become a destination for many people. While the resort has long been dismantled, the area still has some significance in Maryland, since it is the northern starting point for the Maryland section of the Appalachian Trail. To the south of Pen Mar Park is High Rock, a recreational site within South Mountain State Park. The site is close to the Appalachian Trail, features a popular overlook and is used as a hang glider launch site.
