Just 18 miles south on highway 133 is the town of Redstone, where mining has left its indelible mark. Redstone’s historic coke ovens are located on the west shoulder of Highway 133. During the heydey of mining in Redstone, 200 coke ovens were built as a way of refining coal into coke. Although they haven’t been used since the beginning of the 20th century, many of the ovens remain and are a fascinating look into American history. Once in Redstone, take a walk through the quaint town and tour the famous Redstone Castle, a mansion built by John Osgood, founder of the Colorado Fuel and Iron Company. Built in a Stick style with a European-styled interior design and furnishings, the Restone Castle is on the National Register of Historic Places. Guided castle tours are on Saturdays and Sundays at 1:30pm. For more information call (970) 963-9656 or visit http://theredstonecastle.com/.
