A lone torch is housed within the structure.
HOW TO FIND THE STRONGHOLD IN MINECRAFT WINDOWS
There are 16 iron bar windows in the room, and the entrance is always a gate. There are two pools of lava in the front sides of the room and a bigger lava pool below the End Portal. Extremely rare chance of being active, due to generating with 12 Eyes of Ender.
HOW TO FIND THE STRONGHOLD IN MINECRAFT CRACKED
They contain several doors and rooms made mostly of stone brick (45%), mossy stone brick (30%), cracked stone brick (20%) and monster egg blocks (5%). Portal rooms (and other parts of the stronghold) can be overwritten by ravines, caves, abandoned mineshafts, dungeons, or parts of the stronghold itself, forcing a player to find one of the other strongholds. They also attempt to generate under village wells. Very rarely, floating rooms can be found in the ocean. Whole rooms can be flooded if the stronghold is intersected by a mineshaft or ravine. Strongholds primarily generate underground, and prefer to generate in biomes above sea level but will generate underwater if necessary.
