Fifty years ago, Annapolis became a National Historic Landmark District (NHLD), one of the first cities to achieve this status. A National Historic Landmark is a building, site, structure or object that is officially recognized by the United States government for its outstanding degree of historical significance. A National Historic Landmark District is an extension which encompasses an entire historic district. The district may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed.
The Annapolis NHLD encompasses a majority of the colonial historic district. National Historic Landmark’s such as the Maryland State House, St. Anne’s Church, and William Paca House are a part of the historic district.
