Medusa, Maryland's Cultural Resource Information System
Welcome to Medusa!
We are pleased to announce "map-based Medusa," a new interactive map-based tool. It takes advantage of the
rapid development in the last several years of so-called geographic information systems (GIS),
giving us the opportunity to view our extensive geographic database and to access the records
linked to these resources.
Through Medusa, you may access information about architectural and archeological 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. Medusa also
includes information on resources that have been evaluated for National Register
eligibility (Determinations of Eligibility - DOEs).
Archeological records, which include site location information, are available only to professional
archeologists, agency representatives, and researchers working directly with professional
archeologists. Users must have an account with approved permissions in order to access the
archeological records. To request an account,
