on November 22, 1633. The county is the site of the first Catholic Mass celebrated in one of the original thirteen colonies (after they had become English colonies). Earlier dates of masses being said were during 1526–1527 at San Miguel de Gualdape. Due to the small size of the island and its lack of resources, there was no intention to make a permanent settlement on the island. Instead St. Clement's was used as a base for the settlers while scouting for a more suitable site. This was how a bluff overlooking the nearby St. Mary's River was chosen for numerous reasons, and became the site of the first permanent settlement. It would soon be named, " St. Mary's City".
St. Mary's City, Maryland St. Mary's City (also known as Historic St. Mary's City) is a former colonial town that was founded in March 1634, as Maryland's first European settlement and capital. It is now a state-run historic area, which includes a reconstruction of the ...
