Mattapany-Sewall Archeological Site is an archaeological site in St. Mary's County, Maryland. It is located at the Patuxent River Naval Air Station on a level terrace approximately 45' above sea level, less than 1000' south of the Patuxent River in an unused wooded/grassy tract. Documentary evidence identifies the site as Mattapany-Sewall, a manor established in 1663 and occupied from 1666 to 1684 by Charles Calvert, 3rd Baron Baltimore. It served as a governmental meeting place and colonial arsenal, and was the scene of the 1689 battle, known as the Protestant Revolution of 1689, in which Maryland's Proprietary government was overthrown.[2]
It was placed on the National Register of Historic Places in 1985.[1]
