Located on a 66-acre estate on Sarasota Bay, the John and Mable Ringling Museum of Art was established in 1927 as the legacy of John Ringling (1866–1936) and his wife, Mable (1875–1929).

Built brick-by-brick in stages beginning in 1861 by the utopian Oneida Community (1848—1880), the 93,000-square-foot Mansion House testifies to the Community's core belief in the possibility of personal and social perfection. In plan and decoration it reflects popular architectural styles of the mid-19th century, but its large scale epitomizes the needs of a society that lived as one family with more than 300 members. Continually inhabited since 1862, the Mansion House features a museum, overnight lodging, residential apartments, the Zabroso Restaurant in the Community dining room, and banquet and meeting facilities. Century-old trees define the grounds where meandering paths lead to gardens that change with the seasons.

The house offers exhibits, tours, workshops, and educational and recreational programs.

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 year was 1773 and the town of East Greenwich, RI, was still very much a part of English Colonial America. The two-storied frame house being built just above the Kent Country Courthouse was the new home of a young lawyer, James Mitchell Varnum, and his bride, Martha. Built in keeping with the best architectural standards of the day, the new mansion had a hipped roof, modillioned cornices, heavily moulded caps, and a central pedimented doorway with columned porch. The two-storied ell was added sometime in the late 1800s. A fine example of late 18th-century Rhode Island architecture, the Varnum house is on the National Register of Historic Places, and has been furnished throughout with notable pieces from the Revolutionary period. Several of the rooms were restored and furnished by individual Rhode Island familes.

The house offers tours.

Built in 1852 as a middle-class farm house for the family of John and Mary Surratt, the historic Surratt House also served as a tavern and hostelry, a post office, and a polling place during the crucial decade before the Civil War. During the war, it became a safehouse in the Confederate underground system which flourished in Southern Maryland. Today, the museum presents a variety of programs and events, recapturing the history of the mid-19th-century life and focusing on the web of the Lincoln assassination conspiracy and the involvement of the Surratt family.

A second website, maintained by the Surratt Society, can be found here.
