Museum Grants

   The 1881 Courthouse Museum has received several important grants in the last few months. The Oswald Family Foundation has awarded the museum $2000 for our Youth Program. We received a grant of $10,000 from the Mary Chilton DAR Foundation for our preservation project and another $13,000 from the South Dakota State Historical Deadwood Fund Grant to finish much needed structural repairs to the building. We thank all these entities for their support.


2015 Marks Museum Anniversary

   The year 2015 brings with it the observance of the 40th anniversary of the opening of the 1881 Courthouse Museum.

   Following the announcement in 1973 by Custer County Board of Commissioners that a new courthouse would be built and the old building retired, the Custer County Historical Society initiated a petition throughout the county requesting that the old historical building be turned over to the Society and be converted into a museum to preserve the history of the Southern Black Hills.

   Over the next two years, the transformation of Custer County government took place and in the year 1975 the new building was complete and the old courthouse was vacant.  It was that year the museum was born.

   This year, when the Museum opens for the season in May, a flag-raising ceremony will inaugurate the occasion. Thanks to the generosity of Board of Trustees member Chuck Cochran, a replica of the 1881 United States Flag will be raised to fly over the 134 year old structure

   Throughout the year, the Museum staff and volunteers will conduct a variety of observances to mark the 40th anniversary and renew this structure as the permanent repository of the vast and fascinating history of Custer County, South Dakota.
