The Mary Todd Lincoln House is the first site to have been restored in the memory of a First Lady. The 14-room Georgian home was originally built as an inn, completed in 1806, but entered the Todd family in 1832. Mary Todd (1818-1882) lived on this site for seven years (1832-1839). The current furnishings of the home are based on the inventory list of the property's auction following Robert S. Todd's death. Pieces displayed include those previously owned by the Todd and Lincoln families.

The house offers period rooms and tours for students.

John Morgan of Putnam Company originally built the Morgan’s Plantation Log Kitchen in 1846. The building served both armies during the Civil War as both a hospital and kitchen.

Today, the building serves a historic museum, and is furnished with period kitchen artifacts and utensils.

The home offers guided tours during the summer months and during the winter by appointment. The website offers basic visitor information.

The Derby Historical Society seeks to preserve and share the histories of Ansonia, Derby, Oxford, Seymour, and Shelton, Connecticut.

The society offers walking tours and an educational role-playing program designed for fifth graders, the Day in 1972 Program.

The Fort Verde State Historic Park commemorates Fort Verde, which was in use between 1865 to 1891, rendering it an Indian Wars period fortification. By 1865, area settlers had demanded protection from the local Native American peoples, and the Army responded by sending volunteer units—almost entirely of Mexican heritage. A number of original structures still stand. Visitors can enter three historic living quarters (those of the commanding officer, bachelors, and the doctors and surgeons), furnished in the style of the 1880s.

The park offers exhibits, period rooms, an introductory film, and a picnic area.

The Idaho State Historical Society is primarily a state-wide preservation advocacy organization. However, the society does operate the Idaho Historical Museum and an exhibit on military history located in the Old Idaho Penitentiary.

The Fraunces Tavern Museum commemorates the historical use of the Fraunces tavern, originally built as a residence in 1719. After being remade into a tavern in 1762, the structure served as the early Departments of War, the Treasury, and Foreign Affairs, as well as the site of George Washington's 1783 farewell address to the officers of the Continental Army. The museum currently includes the original tavern and four 19th-century buildings. Exhibits include Revolutionary War topics; an 18th-century public dining room, site of Washington's farewell address; and the Clinton Room, named after New York's first governor of American citizenship, George Clinton. Collection highlights include one of George Washington's false teeth.

The museum offers period rooms, exhibits, educational programs on early American taverns and the Revolutionary War, and lectures.

Natural Bridge is the site of the second largest Civil War battle in Florida and where the St. Marks River drops into a sinkhole and flows underground for one-quarter of a mile before reemerging. During the final weeks of the Civil War, a Union flotilla landed at Apalachee Bay, planning to capture Fort Ward (San Marcos de Apalache Historic State Park) and march north to the state capital. With a timely warning, volunteers from the Tallahassee area—Confederate soldiers, old men, and young boys—met the Union forces at Natural Bridge and successfully repelled three major attacks. The Union troops were forced to retreat to the coast and Tallahassee was the only Confederate capital east of the Mississippi not captured by the Union. A reenactment of the battle is held at the park every March.

The park offers occasional recreational and educational events (including living history events).

Custer State Park commemorates the 1874 military expedition of Lt. Colonel George A. Custer (1839-1876). He entered the Black Hills seeking a location for a Dakota Territory frontier post, to map the area, and to catalog its natural resources. These resources included gold, triggering a rush to the area and substantial environmental damage. The park also include The Badger Hole, home of Charles Badger Clark (1883-1957), first South Dakota poet laureate, and the Gordon Stockade built between 1874 and 1875. Clark is best known for his cowboy poetry.

The park offers gold panning demonstrations, hands-on gold panning, tours of The Badger Hole, and interpretive signage near the stockade. The website offers a printable geocaching activity.
