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.

In August 1908, Colonel Allen Allensworth and four other settlers established a town founded, financed, and governed by African Americans. Their dream of developing an abundant and thriving community stemmed directly from a strong belief in programs that allowed blacks to help themselves create better lives. By 1910, Allensworth’s success was the focus of many national newspaper articles praising the town and its inhabitants. Today a collection of restored and reconstructed early 20th-century buildings—including the Colonel's house, historic schoolhouse, Baptist church, and library—once again dots this flat farm country.

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

In this reconstructed 1893 firehouse, the public is shown how the Fort Wayne Fire Department developed from a volunteer department (1839–1882) to an organization of paid professionals (1882–present). This history is traced from the use of hand pumpers and neighborhood volunteers through the development of the steamers and paid firefighters right up to the present-day firefighters. Almost all of the artifacts in the museum were once used by the Fort Wayne Fire Department. Most were graciously donated to the Museum by present and former firefighters or their families in the hopes that future generations can fully understand just how far the fire service has come in the last century and a half.

The museums offers exhibits and tours.

The Society maintains three historical properties, including the Beall-Dawson House, the Stonestreet Museum of 19th-century Medicine, and the Waters House History Center.

Along the shore of Lake Superior, a 7.6-acre expanse of wooded land enfolds the 39-room Jacobean Revival mansion that is Minnesota's premier historic house museum. The interiors of the mansion have endured, boasting nearly all of the same furnishings and décor that graced the rooms when the Congdons' estate was completed in 1908. Even the formal gardens and naturalistic landscape retain much of their original design. Here, visitors are given a look at life in an affluent family home from the turn of the last century.

The site offers tours, educational programs, and occasional recreational and educational events.

The Museum is a tribute to Delaware's native son, Eldridge Reeves Johnson, who founded the Victor Talking Machine Company in 1901.

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 Museum is located in historic Denver Fire Station No. 1. The building was constructed in 1909 for Engine Company No. 1 by Glen W.

Today the Museum offers hands-on activities and exhibits which provide information about fire safety and prevention as well as the history of the Denver Fire Department and historic Fire Station No. 1. Visitors can try on firefighting equipment, slide down a pole, and ride on a fire truck designed just for kids.
