My Lady's Manor is a national historic district at Monkton, Baltimore County and Jarrettsville, Harford County, Maryland, United States. It is a rural or agricultural area, with one village, Monkton. Monkton first developed around a water-powered grist mill and later became a station on the Northern Central Railway. The 10000acres manor itself was established in 1713. Over 60 principal structures, plus numerous important outbuildings associated with them, are included in the district.[1]
It was added to the National Register of Historic Places in 1978.
