The Fox Valley Antiques Show is held twice yearly at the Kane County Fairgrounds in St. Charles, Illinois, the 2nd weekend in March and 3rd weekend in Oct. The Fall Fox Valley Antiques Show, began in 1974, and will mark its 44th year on the third weekend of October 2018. Due to the success of these shows over the years, we have been able to support many historic preservation efforts and educational institutions through gifts and grants.
