The Marbold Farmstead was the hub of the Marbold family, which consisted of over 4,000 acres. It was self-sufficient, with several barns, dairy, chicken house, smoke house, ice house, boiler house and pump house. The original house, called Elmwood, was build in 1850 by John Marbold, a German immigrant and prominent Greenview farmer and businessman. In its day, Elmwood was one of central Illinois' most notable homes.
I was lucky enough to attend the 3rd Annual Marbold Antique Show, held on the farmstead. I also was able to sweet talk myself a private tour, to some of the not-yet-renovated, closed to the public areas. I was escorted by an association member.
[UPDATE: These images are from 2015, so depending on when you view them, more work may have been completed. Always ask before entering a closed off section of the house, and please do not trespass.]
Up until 2012 Marbold Farmstead lay vacant and suffered from years of neglect. In that year, the Historic Marbold Farmstead Association was formed, and purchased the property at auction. Since then, the Association has been in the process of restoring the Main house and attached buildings, stabilized and restored other out buildings on the property, cleaned up the grounds, replanted trees, and much more.
