The Chaska Historical Society was officially organized in 1980 by a group of people who recognized the need to record and preserve the history of Chaska. The Chaska society, a chapter of the Carver County Historical Society, is located in the Chaska History Center on the second floor of the historic Klein mansion at 4th and Walnut just opposite the Town Square. It is led by a nine member elected Board of Directors which meets quarterly. The annual meeting of the membership is held each fall. The dues of the Chaska society also cover membership in the county historical society.
Members have the opportunity to share in many county and local historical programs and events.
The Chaska History Center has become a resource center for researching the history of Chaska and its people through exhibits, photographs, letters, diaries, maps, artifacts, documents and copies of the Chaska Herald newspaper. With the encouragement and cooperation of the City of Chaska, the Chaska Historical Society continues to honor the rich heritage of the Chaska community.
