Fort Washington, located near the community of Fort Washington, Maryland, was for many decades the only defensive fort protecting Washington, D.C. The original fort, overlooking the Potomac River, was completed in 1809, and was begun as Fort Warburton, but renamed in 1808. During the War of 1812, the fort was destroyed by its own garrison during a British advance. The current historic fort—maintained by the National Park Service—was initially constructed in 1824. It is a stone structure with a good cannon shot down the Potomac River. The fort was extensively remodeled in the 1840s and 1890s. The Fort was turned over to the U.S. Department of the Interior in 1946 after its last military personnel departed.The expansive grounds of the present Fort Washington Park, with its extensive hiking/bicycle paths and river view, are a scenic venue for picnicking, fishing, and outdoor recreation. Historical re-enactments are held periodically at the Fort, and there is a small museum. In 2006, repairs were done to shore up the crumbling outer wall, in preparation for the 200th anniversary. The Fort Washington Light, located below the fort, was established in 1857. The current tower, standing 28 feet tall, was constructed in 1882.

Around 1622, the Piscataway tribe, which led the Conoy Federation, built a town they soon called Kittamaqundi on Piscataway Creek near the modern day town of Piscataway, Prince George's County, Maryland.

Piscataway is an unincorporated community in Prince George's County, Maryland, United States. It is one of the oldest European-colonized communities in the state. The Piscataway Creek provided sea transportation for export of tobacco. It is located near the prior Piscataway tribe village of Kittamaqundi.Piscataway 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. It 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. A "Committee of Correspondence" plotted local actions for the American Revolution in Piscataway. One famous resident was William Marbury, involved in a famous early Supreme Court case.During Prohibition in the 1920s, the area was known for the production and sale of moonshine. Some of the product was moved by boat to other areas along the Chesapeake Bay. The creek is now silted in and no longer navigable. The St. Mary's Catholic Church, school, and cemetery are a prominent feature of the community. The complex includes the small 1904 church and a larger 1988 sanctuary. Its parish boundaries include portions of five separate postal towns/communities, giving it the largest territory of any parish in the Archdiocese of Washington. A number of historic houses still survive in the middle of the little town, including a former hotel/tavern, although the last business (the John Wood store) closed in the 1970s. A large development called "The Preserve" is partially opened and is eventually planned to have 1,100 single-family homes. A short bypass road recently opened around the community. The central part of the historic village, centered on a stretch of Floral Park Road, has been listed on the National Register of Historic Places. The poem "The Sot-Weed Factor," by Ebenezer Cooke, mentions details of life in Piscataway during the early colonial period. The same subject was the subject of a novel by the same name by John Barth.

Hard Bargain Farm is the former country estate and working farm of Alice and Henry Ferguson. It is located at 2001 Bryan Point Road in Accokeek, Maryland, overlooking the Potomac River. The property, now a smaller portion of the 330 acres (130 ha) they purchased, was developed by them into a "country garden". Alice Ferguson, an artist, produced a significant body of her work here, and oversaw both the operations of the farm they established, and studied the prehistoric archaeological remains found on the property. (The Accokeek Creek Site, now in Piscataway Park on land donated by the Fergusons, was first studied by her.) The Fergusons established the Ferguson Foundation in 1954 to manage the property. The foundation operates the property as an educational center focused on land stewardship and historical farming practices in the region. The property includes a heavy timber frame tobacco barn originally constructed between about 1830 and 1850, and rebuilt in the post-American Civil War era. Popular events include the annual Oktoberfest, and "theater in the woods" productions. Hard Bargain Farm was listed on the National Register of Historic Places in 2014.
