Biohazard and Pathogen Disinfection in Queen Anne, MD

Queen Anne is an unincorporated community and census-designated place (CDP) in Prince George's County, Maryland, occupying the site of a former port town on the Patuxent River.

Queen Anne was laid out in 1706 under a colonial Maryland act for the advancement of trade and the erection of ports and towns, and it grew to about 150 residents.

The Census Bureau delineated Queen Anne as a CDP for the 2010 census, when its population was 1,280; by the 2020 census the population had risen to 1,405.

Queen Anne covers about 8.7 square miles in the eastern part of Prince George's County, almost all of it land.

In 1747 a tobacco inspection station and warehouse were established at Hazelwood, the estate of merchant Thomas Lancaster; it was one of seven state tobacco warehouses in Prince George's County, and the Hazelwood mansion still stands today, owned by the Maryland-National Capital Park and Planning Commission.

A horse racing track was also built at Queen Anne in the mid-1700s, when the community was a busy Patuxent River port.

Silt washing down from upland farms gradually filled in Queen Anne's harbor; the last cargo ship sailed from the port for England around 1790, and the town declined into a quiet rural community.

During the War of 1812, Commodore Joshua Barney scuttled his Chesapeake Bay Flotilla in the Patuxent River just below Queen Anne to keep the warships from falling into British hands.

The Queen Anne Bridge, originally built in 1755, carried travelers across the Patuxent River between Prince George's County and Anne Arundel County.

In 1897 the U.S. Board on Geographic Names renamed the community Hardesty to avoid confusion with the incorporated town of Queen Anne in Queen Anne's County, but residents kept using the name Queen Anne, and the Census Bureau used the original name when it delineated the CDP in 2010.
