Bon Air Manor or Benson's Park is a historic plantation home located in Ellicott City, Howard County, Maryland.
The Bon Air Manor is a historic gatehouse to the original Benson's Park Manor. Benson's Manor was a 250-acre parcel patented by Daniel Benson in 1696. The property was later expanded to 268 acres.[1] The gatehouse was part of a complex of outbuildings including a barn, stone jail, and slave quarters built in 1805. The property adjacent to the New Cut Landfill has been subdivided for residential development and reduced in size.[2] [3]
