This Saturday at 7pm, there’s a history tour at Tredegar. Though the Tredegar Iron Works is most often associated with the Civil War, it was also part of the “Arsenal of Democracy” in both World Wars of the 20th Century. Join Ranger Mike Gorman for a unique look at the labor issues and production of one of Virginia’s most important industrial sites.
