The Washington Yacht Club is a motorboating club on the Anacostia River in Washington, D.C. Established in 1910 as an all-white organization, the club was integrated in the 1970s, prompting a turnover to predominantly African American membership. In addition to serving as a marina and social club, the Washington Yacht Club has advocated for the environmental protection of the Anacostia, which at one point was one of the most polluted rivers in the United States. The group's clubhouse and surrounding property were listed on the National Register of Historic Places in 2020.

The Pennsylvania Avenue Bridge was a crossing of the Anacostia River in Washington, DC at the site of the present John Philip Sousa Bridge. It was constructed in 1890 and demolished around 1939.

The John Philip Sousa Bridge, also known as the Sousa Bridge and the Pennsylvania Avenue Bridge, is a continuous steel plate girder bridge that carries Pennsylvania Avenue SE across the Anacostia River in Washington, D.C., in the United States. The bridge is named for famous United States Marine Band conductor and composer John Philip Sousa, who grew up near the bridge's northwestern terminus. The first bridge at this location was constructed in 1804, but burned by United States armed forces in 1814 during the War of 1812. It was replaced in 1815, but the bridge burned to the waterline in 1846. The rapid growth of residential developments east of the Anacostia River led to the construction of a narrow, iron girder bridge in 1890. This bridge led to even swifter economic and residential development of the area. Efforts to replace the 1890 bridge with a modern structure began in 1931, but were not successful until 1938. The downstream (southern) span opened on December 9, 1939, to great fanfare. The upstream span was completed in December 1940 and opened on January 18, 1941. The Sousa Bridge has a partial interchange with the Barney Circle traffic circle at its northwestern end, and a partial interchange with Anacostia Freeway at its southeastern terminus. A major battle over building an Inner Loop Expressway in the District of Columbia occurred in the 1950s and 1960s. This led to the partial construction of Interstate 695 from Interstate 395 to Barney Circle, but political battles over the wisdom of further construction led to cancellation of the remaining highway—leaving Barney Circle and the northern approaches to the Sousa Bridge partially deconstructed. An attempt to build the remainder of Interstate 695 (the "Barney Circle Freeway") in the 1990s also failed. In 2010, the District of Columbia decommissioned the portion of Interstate 695 leading to Barney Circle and the Sousa Bridge, and began rebuilding the circle and approaches.

Honfleur Gallery located on Good Hope Road in the Anacostia Historic District neighborhood of Washington, D.C., is a gallery that was established in January 2007 by the Action to Rehabilitate Community Housing group. The art gallery opened amid concerns of whether an art gallery was what the neighborhood needed. By 2014, seven years after its formal opening, local residents were apparently still divided over the impact or reason for the art gallery in the neighborhood. "The neighborhood, long synonymous with urban blight, is an unconventional choice for a swanky art gallery," asserted a 2014 Washington Post article on the gallery.

The Frederick Douglass National Historic Site, administered by the National Park Service, is located at 1411 W Street, SE, in Anacostia, a neighborhood east of the Anacostia River in Southeast Washington, D.C. United States. Established in 1988 as a National Historic Site, the site preserves the home and estate of Frederick Douglass, one of the most prominent African Americans of the 19th century. Douglass lived in this house, which he named Cedar Hill, from 1877–1878 until his death in 1895. Perched on a hilltop, the site offers a sweeping view of the U.S. Capitol and the Washington, D.C., skyline. In 2017 the site was used to represent Washington, D.C., on its America the Beautiful quarter.

The 11th Street Bridges are a complex of three bridges across the Anacostia River in Washington, D.C., United States. The bridges convey Interstate 695 across the Anacostia to its southern terminus at Interstate 295 and DC 295. The bridges also connect the neighborhood of Anacostia with the rest of the city of Washington.The first bridge at the site, constructed about 1800, played a role in the War of 1812. It burned in 1846, but was repaired. A second bridge was constructed in 1873, and replaced in 1907. A modern, four-lane bridge replaced the older bridge in 1965, and a second four-lane bridge added in 1969. In 2009, construction began on three spans (two carrying freeway traffic, one carrying local-only traffic) to replace the 1965 and 1969 bridges. The northbound bridge opened to traffic in December 2011 while the southbound bridge open to traffic in January 2012. The new bridges include new ramps and new interchanges with I-295 (the Anacostia Freeway). The local bridge opened to traffic in May 2012. Portions of all three bridges and their approaches remained under construction into 2013. Phase 1 of the project was completed ahead of schedule and within budget in July 2013. The local bridge was fully complete by September 2013. Phase 2 of the project, including the conversion of the Barney Circle Freeway into a boulevard, was completed in 2015.

Fort Stanton was a Civil War-era fortification constructed in the hills above Anacostia in the District of Columbia, USA, and was intended to prevent Confederate artillery from threatening the Washington Navy Yard. It also guarded the approach to the bridge that connected Anacostia (then known as Uniontown) with Washington. Built in 1861, the fort was expanded throughout the war and was joined by two subsidiary forts: Fort Ricketts and Fort Snyder. Following the surrender of the Army of Northern Virginia, it was dismantled and the land returned to its original owner. It never saw combat. Abandoned after the war, the site of the fort was planned to be part of a grand "Fort Circle" park system encircling the city of Washington. Though this system of interconnected parks never was fully implemented, the site of the fort is today a park maintained by the National Park Service, and a historical marker stands near the fort's original location.
