| Federal Hill Historic District sits on a hill overlooking          downtown Baltimore and the Baltimore Harbor. In 1788, on this hill, the          citizens held a celebration honoring the state’s ratification of the United          States Constitution. An observatory built in 1795 signaled city merchants          of the approach of their vessels, a service that lasted a century. After          intense demonstrations by Northern and Southern sympathizers alike, the          Union Army fortified the hill to protect Baltimore and its harbor. Then,          in 1880, a public park was created in the northern section of the Historic          District.The district contains several hundred 18th- to mid-19th-century residences            grouped alongside Federal Hill Park. The majority are two- and three-story            brick row houses with white marble trim, but visitors to the district            will also find some of the most diverse architecture in Baltimore. In            addition to the homes and park, the Federal Hill Historic District also            includes the Armistead Monument, erected in 1882. The monument honors            Colonel George Armistead, the commander of Fort McHenry when the British attacked in the Battle of Baltimore on September 13,            1814. The Federal Hill Historic District is bounded by Covington, Hughes, Charles, and Hamburg Sts. The district is a combination of private and public buildings, some of which are open to the public. |
