The 1859 Italian Renaissance Revival-style Hay House is a historic house museum, which largely contains pieces from 1926 to 1962. In those years, the Hay family occupied the house. Parks Lee Hay founded Banker's Health and Life Insurance Company. At the time of construction, the house was already outfitted with hot and cold running water, an early intercom system, indoor bathrooms, heating, and a ventilation system. Tours focus on these features and on the architecture itself.

The house offers period rooms, guided tours, traveling trunks for kindergarten through eighth-grade students, nine curriculum-based programs for kindergarten through high school students, homeschool programs, and educational programs for teachers.

The 1880 Jack House and Gardens presents the home of San Luis Obispo, California's Jack family. The Jacks—ranchers, politicians, land developers, and bankers—lived in the home for more than 90 years, and the site is furnished with many of their personal belongings. The home is decorated to interpret Victorian daily life, and the gardens include period varieties of roses.

The house offers period rooms, guided tours, and self-guided gardens tours.

Perched on a cliff on the central California coast, 50 miles south of San Francisco, the 115-foot Pigeon Point Lighthouse, one of the tallest lighthouses in America, has been guiding mariners since 1872. Its five-wick lard oil lamp, and first-order Fresnel lens, comprised of 1,008 prisms, was first lit at sunset, November 15, 1872. The lens stands 16 feet tall, 6 feet in diameter, and weighs 8,000 pounds. It sits in a lantern room that had been constructed at the Lighthouse Service's general depot in New York before being shipped around the Horn. Although the original Fresnel lens is no longer in use, the lighthouse is still an active U.S. Coast Guard aid to navigation using a 24-inch Aero Beacon.

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

The Friendship Fire Company was established in 1774, and was the first volunteer fire company in Alexandria. The current firehouse was built in 1855, remodeled in 1871, and renovated in 1992. The Engine Room on the first floor houses hand-drawn fire engines, leather water buckets, axes, sections of early rubber hose, and other historic fire-fighting equipment. An exhibition discusses the development of firefighting technology and other fire companies that have served the citizens of Alexandria. The second floor Meeting Room is furnished the way it was during the late 19th century, the real heyday of Friendship as a community organization. On view here are various ceremonial objects such as parade uniforms, capes, banners, and other regalia. George Washington's association with the Friendship Fire Company, honored by members for over 200 years, is symbolized by several images of him throughout the museum.

The museum offers exhibits, tours, educational programs, and occasional recreational and educational events.

In 1837, Grover Cleveland was born in this house while his father, the Reverend Richard Falley Cleveland, was the minister to the First Presbyterian Church of Caldwell. Most of the first floor rooms portray the house as it was in 1837. Among the artifacts on display from Cleveland's early years are his cradle and original family portraits. The exhibit gallery features a striking display of artifacts that reflect the financial and political success Cleveland achieved during the last quarter of the 19th century. Here, the mud-slinging campaign of 1884, the public's intense interest in his wife and children, and America's political climate throughout his split terms of office are explored.

The site offers tours, exhibits, educational programs, and research library access.

After railroads made the region accessible in the late 19th century, coastal Maine became a fashionable destination for wealthy summer people. Many of the newcomers bought and restored the fine old houses built during the prosperous years following the American Revolution. In 1898, Mrs. Emily Tyson and her stepdaughter, Elise, purchased the c. 1785 Hamilton House, built on a site overlooking the Salmon Falls River. The Tysons flung themselves into a lifelong project to restore the house to its former glory. Influenced by literary imagery, including the writings of their neighbor and friend, Sarah Orne Jewett, they decorated with a mixture of elegant antiques, painted murals, and simple country furnishings to create their own romantic interpretation of America's colonial past.

The house offers tours and educational and recreational programs.

Wilbor House, the Society's headquarters, stands on land purchased from the Sakonnet Indians in 1673. Built by Samuel Wilbore in about 1690, the original house consisted of only two rooms, one above the other, and a cramped stairway and attic. It was typical of 17th-century New England. Today, one unusual feature of Wilbor House is that it spans three centuries and contains rooms representative of each.

The house offers tours and occasional recreational and educational events.

Wynnewood is the largest extant log structure in Tennessee. It was built in 1828 by A. R. Wynne, William Cage, and Stephen Roberts as a stagecoach inn on the Nashville-Knoxville Road. In 1834, Wynne purchased his partners' interests and moved his family into the inn, where he resided until his death in 1893. Throughout Wynne's lifetime, guests were received at the house, attracted partially by the reputed medicinal powers of the mineral waters and the scenic beauty of the area. Today the spring waters still flow and visitors may see the site where Thomas Sharp ("Big Foot") Spencer spent the winter of 1778–79 in a hollow sycamore tree.

The site offers tours.
