The Widget Fortress was a location on Eternia seen in He-Man and the Masters of the Universe.
The Widget Fortress was home to the Widgets. It was located in the Widget Woods and had originally been built to protect the Widget Mines. In these mines, the Widgets delved various precious jewels, the rarest of which was Coridite.
After He-Man had come to the aid of the tiny Widgets several times, a special signal flare was mounted on top of the ramparts that was designed to shoot a flare shaped like He-Man's breastplate to alert him in times of need.
