Preston-on-the-Patuxent

Preston-on-the-Patuxent is a historic home in Johnstown, Calvert County, Maryland, dating back to around 1725, though traditionally associated with a construction date of 1651. This modest 1+1⁄2-story brick house has undergone several additions and is linked to the Puritan regime, with claims of being the seat of Maryland's government from 1654 to 1657. The property is notable for hosting meetings of the Council, Assembly, and Provincial Court in the 1650s, led by Richard Preston. It was listed on the National Register of Historic Places in 1974, making it a significant site for tourists and researchers interested in early American history.
