The Maryland Historical Trust is proud to sponsor 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 allows access to archaeological records to professional archaeologists, agency representatives, and
researchers working directly with professional archaeologists.
