“Every man wants a castle,” Jim Bishop likes to say. The thing is, he actually built one. Piece by piece, all by himself. Bishop, an ironworker, spent 40 years digging a foundation, felling timber, hauling 1,000 tons of rocks, mixing mortar, and setting stone, to create his very own 160-foot tall castle (sans blueprints). His masterpiece—perched at 9,000 feet in the San Isabel Forest—features domes, turrets, spiral stairs, and even a fire-breathing dragon.
