Maryland Historical Trust

The Maryland Historical Trust is the state agency dedicated to preserving and interpreting the legacy of Maryland’s past. Through research, conservation and education, the Maryland Historical Trust assists the people of Maryland in understanding their historical and cultural heritage. Part of the Maryland Department of Planning, the Maryland Historical Trust serves as Maryland’s State Historic Preservation Office (SHPO) pursuant to the National Historic Preservation Act of 1966. In addition to its administrative office in Crownsville, the Maryland Historical Trust includes the Jefferson Patterson Park Museum in St. Leonard, Maryland, which houses the Maryland Archaeological Conservation Laboratory. The Maryland Historical Trust is open for visitors by appointment and our offices are regularly staffed. Most staff are on a hybrid schedule of in-office and telework. The best way to contact staff is by email.
