Mount Vernon was the beloved home of George and Martha Washington from the time of their marriage in 1759 until General Washington's death in 1799. He worked tirelessly to expand his plantation from 2,000 acres to 8,000 and the mansion house from six rooms to 21. Visitors are invited to tour the Mansion house and more than a dozen outbuildings including the slave quarters, kitchen, stables, and greenhouse. They can stroll four different gardens, hike the Forest Trail, and explore the "George Washington: Pioneer Farmer" site, a four-acre working farm that includes a recreation of Washington's 16-sided treading barn. George and Martha Washington rest in peace in the tomb where wreathlaying ceremonies are held daily, and the Slave Memorial and Burial Ground is nearby.

The site offers multimedia presentations, exhibits, tours, demonstrations, educational programs, river cruises, research library access, and recreational and educational events (including living history events).

This building was the capitol for only four days in 1855, but many believe that the actions of the legislature that met here led directly to the Civil War. Governor Andrew Reeder picked this location, away from the proslavery influence of Missouri, where the legislature would choose a permanent seat of government, create a constitution, and decide if Kansas would be a free or slave state. Instead the legislature kicked out the antislavery members and passed a bill to move the government to Shawnee Mission near the Missouri border. Inside this native stone building visitors will learn the stories of the antislavery and proslavery people of territorial Kansas, set alongside the beauty of the Kaw River Nature Trail.

The site offers exhibits, tours, and educational and recreational events.

The 1678 Joshua Hempsted House is one of New England's oldest and best documented dwellings. Joshua Hempsted lived here his whole life, filling many roles, including farmer, judge, gravestone carver, shipwright, and father of nine children left motherless by his wife's death in 1716. The Hempsted House survived the 1781 burning of New London by the British, commanded by traitor Benedict Arnold. Later, it may have been a safe house on the secret Underground Railroad which aided fugitive slaves seeking freedom. Adjacent to the Joshua Hempsted House is a rare stone dwelling built in 1759 by his grandson Nathaniel. Both houses' furnishings include original Hempsted family objects.

The houses offer exhibits and tours.

The Museum of African American History is dedicated to preserving, conserving, and accurately interpreting the contributions of African Americans in New England from the colonial period through the 19th century. The Museum maintains several individual historical sites, including the Boston African Meeting House, the Abiel Smith School, the Nantucket African Meeting House, and the Higginbotham House. The African Meeting House on Beacon Hill was built in 1806 in what once was the heart of Boston's 19th-century African-American community. It is today a showcase of black community organization in the formative years of the new republic. The 1834 Abiel Smith School is the first building in the nation built for the sole purpose of serving as a public school for black children. This historic site has been transformed into exhibit galleries. The African Meeting House on Nantucket is the island's most vivid reminder of a thriving 19th-century African-American community. Erected in the 1820s by the African Baptist Society (of which Captain Absalom Boston was a trustee), it is the only public building still in existence that was constructed and occupied by the island's African Americans during the 19th century.

The museum offers exhibits, tours, educational programs, lectures, and recreational and educational events; the Boston African Meeting House offers tours; the School offers exhibits; the Nantucket African Meeting House offers exhibits.

At the turn of the 20th century, the J. Thomas Newsome family moved to Newport News. In this industrial city, he established a law practice and prospered as part of the postwar South's new urban, black middle class. Through self-determination and a solid education, Newsome (1869–1942) became a respected attorney, journalist, churchman, and civic leader. His elegant Queen Anne residence served as the hub of the local black community from which he led the fight for social justice within the commonwealth. Today, this restored 1899 Victorian landmark continues to be devoted to the expression of black cultural and historical themes.

The center offers exhibits, educational programs, and occasional educational and recreational events (including living history events).

The Old Slave Mart, located on one of Charleston's few remaining cobblestone streets, is the only known extant building used as a slave auction gallery in South Carolina. Once part of a complex of buildings, the Slave Mart building is the only structure to remain. When it was first constructed in 1859, it has gone through numerous renovations and today serves as a museum, with a permanent exhibition divided into two main areas. In the orientation area, visitors receive an introduction to the domestic slave trade within the greater historical context of slavery in the United States as well an overview of the trans-Atlantic slave trade. In the main exhibit area visitors will also get a closer look at the daily process of slave sales at Ryan's Mart from the perspectives of a number of its historically documented buyers, traders, and enslaved African Americans. This section explains this antebellum slave market's role within Charleston's larger, but concentrated, slave-trading district.

Darnall's Chance House Museum is dedicated to the interpretation and study of the history and culture of 18th-century Prince George's County, MD, with special emphasis on the lives of mid-18th-century women. The Museum interprets the story of the widow Lettice Wardrop Thomson Sim, who lived at Darnall's Chance in the decades just prior to the American Revolution. The house and grounds reflect 1760, the year Lettice Wardrop's first husband died and a room by room inventory was taken of the contents of the house. Darnall's Chance also strives to accurately reflect the African-American community on the site and town life in mid-18th-century Upper Marlboro, MD.

The site offers tours, educational programs, and occasional educational and recreational events.

In August 1908, Colonel Allen Allensworth and four other settlers established a town founded, financed, and governed by African Americans. Their dream of developing an abundant and thriving community stemmed directly from a strong belief in programs that allowed blacks to help themselves create better lives. By 1910, Allensworth’s success was the focus of many national newspaper articles praising the town and its inhabitants. Today a collection of restored and reconstructed early 20th-century buildings—including the Colonel's house, historic schoolhouse, Baptist church, and library—once again dots this flat farm country.

The park offers a short film, exhibits, tours, and occasional recreational and educational events.

The Society maintains three historical properties, including the Beall-Dawson House, the Stonestreet Museum of 19th-century Medicine, and the Waters House History Center. Visitors can learn about the county's beginnings at the historic 1815 Beall-Dawson House, an elegant federal style townhome that features period rooms and changing exhibits. The museum tour highlights the culture and daily life of both the upper-class Beall family as well as the enslaved African Americans who labored in the house and on the adjacent property. The Stonestreet Museum offers an insider's look into the developments in medical science that occurred during the career of Dr. Edward E. Stonestreet. Built in 1852, this unique one-room Gothic Revival doctor's office features medical artifacts and implements that demonstrate the fascinating changes that occurred in the 19th and early 20th centuries. The Waters House History Center is housed in oldest house in Germantown—built in three parts, the oldest dates to the mid-1790s. It offers exhibits related to local history.
