Support the Grant County Historical Society

The Grant County Historical Society is an independent 501(c)(3) non-profit. We operate three history sites which offers the public a rich experience in local history. Our two museum sites are the Grant County History Museum in Lancaster and the 1837 Mitchell-Rountree Stone Cottage in Platteville. We also operate the Grant County Research Center in conjunction with The Grant County Genealogical Society in Lancaster.
