MHT Online Database Portal


The Maryland Historical Trust is proud to introduce Medusa, the State of Maryland's Cultural Resource Information System. Through Medusa, qualified resource professionals are able to access information about resources recorded in the Maryland Inventory of Historic Properties (MIHP) and the National Register of Historic Places (NRHP), as well as properties on which MHT holds preservation easements and information on resources that have been evaluated for National Register eligibility (Determinations of Eligibility, or DOEs). The system will allow access to archeological records to professional archeologists, agency representatives, and researchers working directly with professional archeologists.

The links below lead to specific searchable databases. These are designed for public as well as professional use. Use them to browse the National Register and the Historic Markers Program.
