Medusa, Maryland's Cultural Resource Information System

Welcome to Medusa!

"Map-based Medusa" is an 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 archaeological 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).

Archaeological records, which include site location information, are available only to professional archaeologists, agency representatives, and researchers working directly with professional archaeologists.  Users must have an account with approved permissions in order to access the archaeological records.
