Old Town San Diego State Historic Park presents the opportunity to experience the history of early San Diego by providing a connection to the past. Visitors can learn about life in the Mexican and early American periods of 1821 to 1872, as converging cultures transformed San Diego from a Mexican pueblo to an American settlement. The core of restored original historic buildings from the interpretive period are complemented by reconstructed sites, along with early 20th-century buildings designed in the same mode. The Historic Plaza remains a gathering place for community events and historic activity. Five original adobe buildings are part of the historic park, which includes museums, unique retail shops, and several restaurants. La Casa de Estudillo is a mansion built around a garden courtyard. La Casa de Machado y Stewart is full of artifacts that reflect ordinary life of the period. Some of the other historic buildings include the Mason Street School (California's first public schoolhouse), La Casa de Machado y Silvas, the San Diego Union Printing Office (site of the city's oldest surviving newspaper office), and the first brick courthouse. The Seeley Stables Museum, with newly rehabilitated exhibits on overland transportation, houses one of the finest wagon and carriage collections. Visitors can experience a working blacksmith shop, enjoy music, see or touch the park's burros, and engage in activities that represent early San Diego.

The park offers exhibits, tours, living history events and programs, and other recreational and educational events.

The Society was organized in 1976 and is located in the historic residence of Senator Knute Nelson (1843–1923).

The society offers tours of the house, research library access, and occasional educational and recreational events.

Glimpses into two of the U.S.'s wars can be found in one historic site within the city of Kinston. Here visitors can explore the celebrated life of Richard Caswell, the first governor of the independent state of North Carolina. They can also see up close the remnants of the ironclad gunboat CSS Neuse, a product of the Confederate Navy's ill-fated attempt to regain control of the lower Neuse River and retake the city of New Bern during the Civil War.

The site offers a short film, exhibits, tours, and occasional recreational and educational events (including living history events).

The Sewall-Belmont House and Museum explores the evolving role of women and their contributions to society through the continuing, and often untold, story of women's pursuit for equality. The museum is the headquarters of the historic National Woman's Party and was the Washington home of its founder and Equal Rights Amendment author Alice Paul. Sewall-Belmont, named in the first Save America's Treasures legislation, is the only museum in the nation's capital dedicated to preserving and showcasing a crucial piece of our history—the fight for the American woman's right to vote. This struggle is documented through one of the most significant collections in the country focused on the suffrage and equal rights movements.

The museum offers a short film, exhibits, tours, educational programs, forums, and research library access.

The grounds of this site include several historic structures, including the Tryon Palace, the George W. Dixon House, the Stanly House, the Robert Hay House, and the New Bern Academy. Tryon Palace was originally built between 1767 and 1770, as the first permanent capitol of the Colony of North Carolina and a home for the Royal Governor and his family. Josiah Martin, the second royal governor to live in the Palace, fled in May of 1775 at the beginning of the American Revolution. Patriots made the Palace their capitol and the first sessions of the General Assembly met there to begin designing a free and independent state. Four state governors used the Palace: Richard Caswell, Abner Nash, Alexander Martin, and Richard Dobbs Spaight. The George W. Dixon House was built in the early 1830s for George W. Dixon, a merchant tailor and one-time mayor of the city of New Bern. The Stanly House was built in the early 1780s for John Wright Stanly, a prominent New Bern citizen. John Hawks, the architect who designed Tryon Palace, may have designed the Stanly House as well. Built of hand-hewn longleaf pine, the Stanly House remains one of the finest examples of Georgian architecture in the South. The Robert Hay House, built in the first decade of the 19th century, is modest by comparison to other homes on the Palace complex. Robert Hay, a Scottish immigrant and wagon maker, bought this Federal-style wood frame townhouse in 1816, the same year he married Nancy Carney, and resided there until his death in 1850, at the age of 96. Today, it functions as a "living history" museum. Visitors get a firsthand feel for life in 1835 by talking with character interpreters who portray Hay household members and neighbors, and by hands-on experiences with the reproduction furnishings of this "Please Touch" museum. The New Bern Academy was the first school in North Carolina to be established by law; the legislative assembly incorporated it in 1766. Fire destroyed the original building in 1795. The present building was constructed between 1806 and 1809, and served as a school until 1971, making it one of the oldest continuously used school buildings in America. Today, it serves as a museum of local history.

The sites offer a short video, exhibits, tours, demonstrations, performances, and educational and recreational events (including living history events).

The Foundation operates two historical sites, Historic Kenmore and Ferry Farm. Built by George Washington's sister, Betty Washington Lewis and her husband Fielding Lewis, Kenmore, a 1775 Georgian-style mansion, reflects the pre-Revolutionary War wealth and status of the Fredericksburg merchant. Lewis lost his fortune due to his patriotic support of the war but the house he built remains. Ferry Farm is the boyhood home of George Washington. Augustine Washington moved his family to this property in 1738, when his son, George, was six years old. George received his formal education during his years here, and forged friendships in the neighborhood that lasted the rest of his life. In 1754, George moved to Mount Vernon while his mother, Mary Ball Washington, stayed on at the farm until 1772, when she moved to Fredericksburg.

The foundation offers educational programs and occasional recreational and educational events (including living history events); Kenmore offers tours; Ferry Farm offers exhibits and tours.

A Hawaiian national treasure and the only official state residence of royalty in the United States, 'Iolani Palace was the official residence of the Hawaiian Kingdom's last two monarchs—King Kalakaua, who built the Palace in 1882, and his sister and successor, Queen Lili'uokalani. During the monarchy period, the Palace was the center of social and political activity in the Kingdom of Hawai'i.

The palace offers tours, exhibits, concerts, educational programs, other workshops and classes, and occasional educational and recreational events.

William B. Ide was named president of the short-lived California Bear Republic—which lasted for 22 days. The adobe memorial to him is located in a picnic area overlooking the Sacramento River. The park features the old adobe home, carriage shed, blacksmith shop, and a small visitor center.

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

The President Benjamin Harrison Home is the former residence of President Benjamin Harrison (1889 to 1893). The museum is dedicated to his achievements
and his impact on United States history.

The Farmington River Valley landmark of Heublein Tower sits atop Talcott Mountain, a long, precipitous wooded ledge named after the Talcott family. The 165-foot structure was built as a summer home in 1914 by Gilbert Heublein. In the early '50s, two future presidents were guests of the Hartford Times, then General Dwight D. Eisenhower (who was asked to run for office there) and Ronald Reagan, then president of the Screen Actors' Guild. Following a period of ownership of the property by the Hartford Times during WWII and the early 1950s, it was slated for residential development by a private corporation when the 557 acres of Talcott Mountain came under public ownership in 1965 through the cooperative efforts of private conservationists and state and federal governments.

The park offers tours.
