A black, castle-like mansion. The building that is made out of stone and timber can be seen to possess the statue of a Dragonite upon the front lawn. Gate spikes open a path for those to walk through. Past the statue, there is a large door knocker with the head of a Gyarados upon a black steel door. When entry has been given you will be escorted to the rooftop. A simplistic gym field, the purpose of its design is so that destruction and casualty are minimal. The reason as to why the entire mansion is painted black is so that scuffles, dents, and soot from previous battles aren't easy to be seen; along with the fact that there may be Sky Battle's that occur every once in awhile. It's because of the Gym Leader's aggressive nature that his Pokemon, too, take after him.
