When Joseph Priestley (1733–1804) is remembered today, it is usually for his 1774 discovery, in England, of oxygen. Few know he was a noted theologian, political progressive, and prolific author whose scientific contributions include the development of the carbonation process, the identification of carbon monoxide, and early experiments in electricity. He counted Benjamin Franklin, Thomas Jefferson, and James Watt among his friends. Yet Priestley was also a controversial figure whose views were so odious to some of his countrymen that his house, Fair Hill in Birmingham, was burned in a riot, and he and his family left England. Priestley spent the last 10 years of his life in Northumberland, PA, where he continued his work in science, religion, and education. But even in this democratic republic his liberal ideas were frequently received with intolerance, and the peace that he so ardently desired was often elusive. Today, the Joseph Priestley House is an historic site that preserves and interprets the contributions and significance to American history of Joseph Priestley, noted English theologian, educator, natural philosopher, and political theorist.

The house offers a short film, exhibits, tours, educational programs, research library access, and occasional recreational and educational events (including living history events).

Los Encinos State Historic Park was the hub of Rancho El Encino. Located in the San Fernando Valley, this California rancho includes the original nine-room de la Ossa Adobe, the two-story limestone Garnier building, a blacksmith shop, a natural spring, and a pond. Located along a significant travel route between Los Angeles and Santa Barbara, the property passed through many hands between the 1840s and the early 20th century. Today, the park contains exhibits related to the agricultural enterprises of Rancho El Encino's various owners, including Mission Indian, Mexican Californio, French, and French Basque families.

The site offers exhibits, tours, and living history events.

Jefferson Patterson Park and Museum (JPPM) is the state archeological museum of Maryland and is located on 560 scenic acres along the Patuxent River in Calvert County, Maryland. JPPM is home to the Maryland Archaeological Conservation Laboratory, which houses over 8 million artifacts which are available for research, education, and exhibit purposes to students, scholars, museum curators, and educators. JPPM is also a vibrant center for education.

School groups learn about Native American and Colonial history and archaeology. Visitors enjoy workshops on pottery, basketry, carving or sewing, talks about the history of the Chesapeake Bay region, or exhibits “FAQ Archaeology” and "The War of 1812." Behind the scenes tours of the Maryland Archaeological Conservation Laboratory show how artifacts are treated and studied. Maryland educators can rent a 4th-grade travelling trunk on Eastern Woodland Indian Cultures. Downloadable teacher resources, including pre- and post-visit activities, are available on the museum's website.

The 128-acre Grand Village of Natchez Indians was the key ceremonial site of the Natchez people between 1682 and 1729. At the end of this period, the Natchez attacked the French who had settled in their homeland, southwest Mississippi. The French secured such a decisive victory that the Natchez were permanently dispersed in 1729. The Natchez people had called southwest Mississippi their home from as early as approximately 700. The Natchez were farmers, hunters, and gatherers; and their society was organized into two moieties, with membership determined by matrilineal inheritance. The site includes a museum, a reconstructed Natchez dwelling, and three earthen mounds—the Great Sun's Mound, the Temple Mound, and the Abandoned Mound. The Temple Mound once supported a temple which housed the remains of Natchez leaders.

The village site offers exhibits, a reconstructed period dwelling, a nature trail, a children's hands-on area, group tours, and student educational programs. Reservations are required for group tours and educational programs.

The historic town of Sonoma is located in the heart of the beautiful wine country between Napa and Santa Rosa off Highway 12. Situated around a central plaza (the largest of its kind in California) filled with shops and restaurants, the city is home to Sonoma State Historic Park—site of the northernmost Franciscan Mission in California and birthplace of the California State Bear Flag. Unlike most parks with a plot of land and geographical boundaries, Sonoma State Historic Park is a series of historic attractions in several locations within the community. The park is comprised of six sites: the Mission San Francisco Solano; the Blue Wing Inn; the Sonoma Barracks; and the Toscano Hotel, as well as La Casa Grande and Lachryma Montis, the homes of General Mariano Guadalupe Vallejo, Military Commander and Director of Colonization of the Northern Frontier.

The park offers exhibits and tours.

Known historically as "the Gateway to the Dakotas," Fort Abercrombie was the first permanent United States military fort established in what was to become North Dakota. It was also the only post in the area to be besieged by Dakota (Sioux) warriors for more than six weeks during the Dakota Conflict of 1862. During the Dakota Conflict, Minnesota Volunteer soldiers manned the fort when area settlers sought shelter there. The "regular" U.S. Army soldiers had been withdrawn during the Civil War and had been replaced by the Minnesota Volunteer Infantry. The fort was not protected by blockhouses or a palisade during the seige, but these defensive structures were constructed soon afterward. The fort guarded the oxcart trails of the later fur trade era, military supply wagon trains, stagecoach routes, and steamboat traffic on the Red River. It also was a supply base for two major gold-seeking expeditions across Dakota into Montana. Fort Abercrombie served as a hub for several major transportation routes through the northern plains.

Bishop Hill was the site of a utopian religious community founded in 1846 by Swedish pietist Eric Janson (1808–1850) and his followers. A number of historically significant buildings have survived and are scattered throughout the village, four of which are owned by the state and managed as part of the Bishop Hill State Historic Site. The 1848 Colony Church is a two-story frame building. The three-story stuccoed-brick 1850s Colony Hotel served commercial travelers and provided a link to the outside world. The 1850 "Boys' Dormitory" is a small two-story frame structure believed to have provided housing for boys making the transition to working adulthood. An 1850s Colony barn was relocated behind the Hotel to the site of the original Hotel stable. In addition to the historic structures, the state owns the village park with a gazebo and memorials to the town's early settlers and Civil War soldiers. The brick museum building houses a valuable collection of primitivist paintings by colonist Olof Krans (1838–1916).

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

In 1839 a Swiss immigrant named John Sutter received a land grant in the Sacramento Valley from the Mexican government. He used the land to create a flourishing agricultural empire and named it New Helvetia (New Switzerland.) This empire established Sacramento's earliest settlement and the first non-Indian settlement in California's Central Valley. In 1847, Sutter sent aid to the Donner Party, a group of immigrants trapped in a winter storm in the Sierra Nevada Mountains. Word spread and Sutter became known for his hospitality and for providing temporary refuge to travelers. This reputation made New Helvetia the destination for early immigrants to California. Less than a decade after they were established, Sutter's properties were overrun by gold seekers and the fort is all that remains of New Helvetia. It has been restored to its former state based on an 1847 map published in Darmstadt, Germany and is open daily for tours.

The park offers exhibits; tours; and recreational and educational events, including living history events.

The temple is the oldest continuously used Chinese temple in California. On display are art objects, pictures, mining tools, and weapons used in the 1854 Tong War. This Taoist temple is still a place of worship and a fascinating look into the role played by Chinese immigrants in early California history. The temple was built in 1874 as a replacement for another that had burned. Many of the historical objects have been restored and the structure itself stabilized.

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