Broad Creek in Prince George's County was the first footprint of European settlement in the immediate counties around what would become the nation's capital, Washington, D.C. The area is part of greater Fort Washington. The area was settled by Europeans in the 1660s and the town was created in 1706 when the colonial Maryland Legislature authorized surveying and laying out the towns of Queen Anne Town, Nottingham, Mill Town, Piscataway, Aire (also known as Broad Creek) and Upper Marlboro (then known as Marlborough Town).In 1747, the legislature tried to improve the quality and the method of marketing tobacco, then the major crop of the area, and established a formal system of tobacco inspection and quality control. The town was home to one of seven state tobacco warehouses built in Prince George's County.The site is located 9 miles (14 km) south of the U.S. Capitol building on the Potomac River. Today, this "first footprint" of settlement in the capital area is a Prince George's County Historic District, with three 17th century homesites and an 18th-century Episcopal Church structure. The Broad Creek Historic District comprises 900 acres (3.6 km2) along the Potomac River, and is remarkable for its environmental resources, as well as its 12,000-year-old Indian archeological discoveries. It was placed on the National Register of Historic Places on December 8, 2011.

Harmony Hall, located in Fort Washington, Maryland, is managed by the United States National Park Service as part of the National Capital Parks-East system. It has been a National Park Service site since 1966. Harmony Hall is a 2+1⁄2-story Georgian country house built of red brick during the eighteenth century. It is surrounded by 65 acres (26 ha) of land on Broad Creek, a Potomac River tributary.The house was built circa 1769 by Enoch Magruder. After his death, the estate was given to his daughter, Sarah and her husband, Col. William Lyles. The estate was originally called Battersea, but came to be called Harmony Hall some time after 1792, when it was rented to brothers John and Walter Dulaney Addison and their wives. The name "Harmony Hall" commemorates the two couples' harmonious coexistence. Harmony Hall was sold by the Lyles family in 1850. After passing through other owners, the manor was purchased in about 1892 by Robert Stein, his brother Richard, and brother-in-law Joseph Adler. The three had immigrated from Silesia, and engaged in truck farming nearby. They lost control of the manor house in 1929, selling it to Charles Collins, but continued to farm and operate a general store in the area.The home was extensively restored beginning in 1927 by Charles Wallace Collins (1879–1964), a lawyer, writer, and librarian who made his home in Harmony Hall and devoted himself to its restoration after he retired. Collins bequeathed the house to the National Park Service.Beginning in 1985, Frank Calhoun leased the mansion and lived there, investing more than $1 million into the house and its upkeep. After he fell behind on renovations in his early 60s, the Park Service asked Calhoun to leave in 1999. The property has been empty and in accelerating decline since then. Though the Park Service periodically sends in staff and enlists students to clean up the grounds, Harmony Hall competes with many other historic properties for attention and funding.The home has been listed on the National Register of Historic Places since 1980, at which time its condition was described as "excellent". As of January 2010, Harmony Hall is closed to the public.Harmony Hall is also the name given to a community center building, on adjacent property, owned by the Maryland-National Capital Park and Planning Commission and used as their southern area headquarters office. The center includes a fitness center and hosts concerts, stage plays, art exhibits, arts classes, scout meetings, and other cultural programs. The building was originally an elementary school.

Rosecroft Raceway, nicknamed the "Raceway by the Beltway" for being close to Interstate 495, is a harness racing track in Fort Washington, Maryland. It first opened in 1949 and was owned by William E. Miller, a horse trainer and breeder. Rosecroft quickly became Prince George's County's political and social center, drawing thousands of people there each racing day. In the early 1950s, average attendance was more than 7,000 per day. After Miller died in 1954, his son John owned Rosecroft until his death in 1969. Rosecroft hosted memorial stake races annually for both William and John until 1995. Following the death of John Miller, Earle Brown controlled operations until he moved to a different position in 1980; William E. Miller II took over following Brown. Rosecroft was sold to Mark Vogel in 1987. Vogel made several mistakes that hurt the horse racing industry in Maryland. Three years later, he was arrested for possession of cocaine, and his company went into bankruptcy. Rosecroft was sold to Weisman's Colt Enterprises in 1991. In that same year, the grandstand caught fire and was reconstructed in 1993 for $3.6 million. In 1995, after losing millions, the relatives of Weisman sold Rosecroft to Cloverleaf Enterprises. In the 2000s, Cloverleaf attempted to sell Rosecroft multiple times, but due to lawsuits and politics, all the potential buyers became uninterested. Nearby states legalized casinos to help their racetracks. Money generated from the casinos was used to increase the purses and handle (daily betting turnover), and Rosecroft was unable to produce the same amount of money. After filing for bankruptcy once again, Rosecroft Raceway closed down in 2010. The next year, Penn National Gaming purchased the racetrack with the hope to make it a racino, and Rosecroft reopened in 2011. Throughout Rosecroft's history, it has featured notable races. From 1984 to 1988, it hosted segments of the Breeders Crown. Starting in 1990 and ending in 1995, the racetrack hosted the Messenger Stakes, the second leg of the Triple Crown of Harness Racing for Pacers. Rosecroft hosted the Potomac Stakes, Maryland most successful harness race, from 1990 to 1992. Rosecroft features the Maryland Sire Stakes, which showcases the best standardbred horses in Maryland. Besides the races, Rosecroft has had famous people and horses work and race at the track. John Wagner, Maryland's all-time most winning driver, has been working at Rosecroft since 1974. Several famous people—Lyndon B. Johnson, Elizabeth Taylor, and Nancy Pelosi, among others—have visited Rosecroft. Cam's Card Shark raced at Rosecroft in 1994 and challenged the single-season record for most money won in a season by winning over $2 million, and Robust Hanover set a track record while winning the Breeders Crown in 1985.
