Cardiff is a ghost town in Livingston County, Illinois, United States. Founded as a coal mining town in 1899, it boomed in its first few years. Rapid growth ceased after accidents in the mines in 1903, and the closure of the mines in 1912 soon led to the community's demise. An official state historical marker has been created on the site of the town, paver bricks that can be engraved with names of the donors are still available for purchase for $75 and are installed pretty quickly into the memorial patio at the marker site.
