About the Charles County Tour
Founded in 1658 and named for Charles Calvert, the third Baron Baltimore, Charles County is a place where Maryland’s colonial and religious roots run deep. Established as a refuge for English Catholics seeking peace and coexistence, the county is home to the oldest Catholic parish in the United States, which continues its mission today. During the Revolutionary War, Charles County played a vital role by providing troops, supplies, and leadership to the cause of independence. The Maryland House and Garden Tour of Charles County invites you to explore historic homes that reflect centuries of American history, from early colonial settlements to the patriotic spirit that helped shape a new nation, all set against the county’s enduring rural landscape.
