The National Register of Historic Places recognizes districts, buildings, structures, objects, and sites for their significance in American history, archeology, architecture, engineering, or culture, and identifies them as worthy of preservation. The National Register is a program of the U.S. Department of the Interior, National Park Service, and is administered at the State level by the Maryland Historical Trust. The National Register currently comprises over 1300 listings in Maryland, including some 200 historic districts. Listed properties span a wide variety of types and periods, ranging from prehistoric archeological sites to buildings of the recent past, and include rural landscapes, urban and suburban neighborhoods, bridges, sailing vessels, and more.

The National Register geospatial dataset is intended to be a comprehensive inventory of all cultural resources that are listed on the National Register of Historic Places. However, this dataset excludes all features deemed 'restricted' or 'sensitive', such as sensitive archaeological sites. This dataset provides feature geometry representations (point or polygon) and is intended to be supplemented with descriptive attributes maintained by other external database systems such as the National Register Information System which is included in this geodatabase.
