The Association operates several museums and historic sites, including the Whaling Museum, Hadwen House, Oldest House, Old Mill, Old Gaol, Quaker Meeting House, and the Hose-cart House. The Museum displays exhibits tracing the history of the New England whaling industry. The Hadwen House is a Greek Revival mansion built in 1845 by whaling merchant and silver retailer William Hadwen. Also called the Jethro Coffin House, the Oldest House is the oldest residence on Nantucket. Built as a wedding gift in 1686 for Jethro Coffin and Mary Gardner, it is the sole surviving structure from the island's original 17th-century English settlement. The Old Mill, built in 1746 by Nathan Wilbur, a Nantucket sailor who had spent time in Holland, is the oldest functioning mill in the country. The Old Gaol was opened in 1806; the wooden structure represents colonial architecture with exceptional reinforcements. The Quaker (Friends) Meeting House was erected in 1838 and originally served as a Friends School for the Wilburite Sect. The Fire Hose-cart House is the last remaining 19th-century firehouse on the island, dating from 1886.

The association offers tours, lectures, classes, research library access, and recreational and educational events; the Museum offers exhibits; the Hadwen House offers tours; the Oldest House offers tours; the Old Mill offers tours and demonstrations; the Old Gaol is open to the public; the Quaker Meeting House is open to the public and offers lectures; the Hose-cart House is open to the public.

The Burra Burra Mine site consists of 10 buildings located on 17 acres and is listed in the National Register of Historic Places. The mine was in operation from 1899 to 1959. The site was also the mining company's surface headquarters from 1902 to 1976. Buildings on the site include the mine office, shop building, change house, hoist house, and powder house. Copper mining took place in the Ducktown Basin, site of the Burra Burra Mine and several other mines, from 1850 to 1987. The Burra Burra Mine received its name from the basin's copper deposit, which in turn was named for a copper deposit of similar size in Australia. The museum interprets the basin's history through audiovisual and artifact exhibits and examples of the kinds of equipment used in the mines. The history of the Cherokee Nation, including its removal from the basin, is also presented.

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.

Cracker Country, a rural Florida outdoor living history museum was established so that future generations might better understand and appreciate Florida's rural heritage. From the rustic cypress log corn crib to the grand old two-story Carlton house, Cracker Country features 13 original buildings dating from 1870—1912. These buildings were moved to their present location from throughout the state, then restored and furnished with antiques of the period.

The site offers exhibits, tours, and demonstrations.

Organized in 1925, the mission of the Lake County Historical Society is to preserve the history of Lake County, MN, through the preservation, study and interpretation of artifacts, documents, photographs, and historic sites. The Society also maintains several historic sites. The Two Harbors Light Station constructed in 1892 is the oldest operating light station in Minnesota and is listed on the National Register of Historic Places. The lighthouse museum explores the development of Agate Bay. The 3M Museum includes the original office and headquarters of Minnesota Mining and Manufacturing (3M). It was here, in 1902, that five businessmen embarked on a mining venture which laid the foundation for a successful global corporation. Exhibits include Attorney John Dwan's recreated office; a history of the company including photos, artifacts, and documents; a "lab" area representing research and development, product diversification, and growth; and a "hands on" interactive program of technology applications. The Depot Museum is in the 1907 headquarters of the Duluth and Iron Range Railroad, and highlights the early pioneering history of Lake County. Exhibits range from McDougal archaeological dig artifacts and a Paleo-Indian display to the first shipment of iron ore from Minnesota.

The Two Harbors Light Station offers exhibits and tours; the 3M Museum offers exhibits; and the Depot Museum offers short films and exhibits.

This Powder River was the vein of life during the boom days of the gold rush. The landscape still bears the scars. Miles of tailings line the banks of the river, a remembrance from the prosperous days of mining. The Sumpter Valley Dredge left much of the rocky footprint that visitors can see on their trek along Highway 7. The dredge is an important link to Oregon's pioneering past and development. It is one of the largest and most accessible gold dredges in the U.S., and the last of three built on the Powder River. Built in 1935, it ran until 1954. It dug up more than four million dollars worth by a simple, but dramatic method.

The site offers interpretive services, according to the website; however, the services are not described.

The newest State Monument tells the fascinating story of more than three centuries of trade and commerce that traversed the trail, linking Spain, Mexico, and the United States at a time when mules, trains, and horses were the only means of land travel. The award-winning building is set amidst the pristine Chihuahuan Desert north of the Jornada del Muerto and houses an exhibit that takes visitors on a virtual journey along the historic trail from Zacatecas, Mexico to Santa Fe, New Mexico. Visitors can discover the indigenous people encountered by the Spanish and the impact the arrival of the Spanish had on the formation of New Mexico. Remnants of the early journey remain today in hand-hewn carts, tools, leather water jugs, and religious altars and objects that accompanied the travelers into the northern territory. Visitors experience the journeys of Native Americans, Spaniards, and Mexicans; the military fort period; and the first Anglo settlers from the Eastern United States, through first-person stories and the art and objects they brought with them.

A second website, maintained by the El Camino Real International Heritage Center Foundation, can be found here.

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

Historic Ritzville maintains two museums. The Burroughs Home was the residence of Ritzville's pioneer physician, Dr. Frank R. Burroughs. It has been restored to its original condition and its collection highlights clothing and household items from the 1890s to the 1920s. The Depot features commercial artifacts relevant to Ritzville around the turn of the century. These include the town's original horse-drawn hearse and a working telegraph machine.

The museum offers exhibits and educational programs, in which students learn about history and other subjects while making crafts and conducting experiments.

Completed in 1841 when Florida was still a territory, the Union Bank is the state's oldest surviving bank building. Chartered to help finance local cotton plantations, it ultimately closed because of crop failures, the Second Seminole War, and poor management. After the Civil War, it reopened as the Freedman's Savings and Trust Company for emancipated slaves and later served several other functions. In 1971, the Bank was moved from its original site, and, after restoration, it was opened as a museum in 1984. The Union Bank now serves as an extension of the Florida A&M University Black Archives, Research Center, and Museum and is open to the public and school groups only on weekdays. Artifacts and documents reflecting black history and culture are on display, and public programs are provided by Black Archives staff.
