The Prince George's County Sheriff's Office (PGSO), officially the Office of the Sheriff, Prince George's County, provides law enforcement services in Prince George's County, Maryland in the United States. Its headquarters are located in Upper Marlboro, near the Depot Pond. The sheriff is the chief law enforcement officer of Prince George's County and is elected every four years. There are no term limits for the sheriff.Created in 1696, the traditional duties of the sheriff are keeper of the public peace and the enforcement arm of the county court, analogous to the U.S. Marshals Service. The PGSO has a relatively long history compared to other police departments and sheriff's offices in Maryland. The PGSO was involved with events that occurred during the burning of Washington and affected the writing of "The Star-Spangled Banner". Prior to 1931, the PGSO was the sole law enforcement organization of the county.Today, the duties of the sheriff include law enforcement services of the two county courthouses and surrounding property, service of court-ordered warrants, writs, protective orders, and other injunctions, and limited patrol responsibility with the County Police. The Domestic Violence Unit has expanded its role in the county to include responding to calls for service that are domestic-related. The creation of the School Resource Deputy division has placed a deputy sheriff at all of the local high schools, replacing the County Police. All other law enforcement services of the county are provided by multiple agencies but mostly left to the separate Prince George's County Police Department (PGPD), though some responsibilities are shared by both agencies. The PGSO, like most other county-level law enforcement agencies in the United States, is a progressive agency with an array of services, from the Specialized Services Team (dealing with high-risk arrest warrants and barricaded situations) to community services aiding the county's residents in safety education. The PGSO was accredited for the first time by the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA) in 2018.

Pinkett founded the airport in Croom, Maryland, in Prince George's County on leased land near the Patuxent River. It housed up to five runways, three hangars, ten planes, and an all-black chapter of the Civil Air Patrol. The airport was operated from 1941-1954 by John William Greene Jr, and also by Tuskegee Airmen, Herbert Jones Jr., who would later form International Air Association, the first African-American owned airline.In 1959, the property was purchased by the Maryland-National Capital Park and Planning Commission and became the first part of the Patuxent River Watershed Park.

Mount Pleasant is 2+1⁄2-story brick structure with a gambrel roof and is about two-thirds its original length. It is located near Upper Marlboro in Prince George's County, Maryland. Mount Pleasant was patented in 1697 to Richard Marsham, whose wife Anne was the daughter of Leonard Calvert, Governor of Maryland. Their grandson, Marsham Waring, inherited the home from his grandfather in 1713. His son, Richard Marsham Waring had a son, Richard Marsham Jr., born in 1733, who then inherited Mount Pleasant and Patented and Certified the tract of land dubbed "Mount Pleasant Enlarged" in 1760. On August 21, 1764, Richard Marsham Jr. sold the 451+3⁄4 acre tract of land to his brother John for £474.6s.9d. John later built the standing house in the years between 1764 and 1785 (conflicting dates). John died in 1813 and was buried at Mount Pleasant.Mount Pleasant is an example of an almost distinctively Maryland style of house—the English gambrel roof dwelling in brick, with the steep gambrel which has dormers almost flush with the second pitch of the roof. This house is significant primarily for its architecture and as a representative example of a more modest type of mid-Georgian dwelling than others in Maryland such as Montpelier, and probably a closer reflection of the architectural ancestry than the Palladian country house. As a more modest dwelling Mount Pleasant is an unusual survivor.Thomas Fielder Bowie is interred in the Waring family burial ground on this site.
