Additional "passages" between rooms may exist if their generation overlaps or if the stronghold intersects a cave, mineshaft, or other structure. Rooms may have exits to other room pieces or dead-end "exits" into stone. Each room has an entrance, which is either a plain 3×3 opening, a wall with a wooden door, a wall with an iron door (with buttons), or a 3×3 opening with a gate of iron bars along the top and sides. Strongholds feature various types of main rooms. In generated chest corridors and storerooms, dispersed chests containing a variety of loot can be found. Stairs that generate within these structures include stone brick and cobblestone stairs, but not their mossy variants. Strongholds are lit by enough torches to provide visibility in most areas, though not enough to suppress mob spawns.

Infested cracked stone bricks and infested mossy stone bricks do not generate, unless silverfish enter these blocks. They contain several doors and rooms made mostly of stone bricks (45%), mossy stone bricks (30%), cracked stone bricks (20%) and infested stone bricks (5%). The eighth and outermost ring has 9 strongholds within 22,784-24,320 blocks of the origin.The seventh ring has 36 strongholds within 19,712-21,248 blocks of the origin.The sixth ring has 28 strongholds within 16,640-18,176 blocks of the origin.The fifth ring has 21 strongholds within 13,568-15,104 blocks of the origin.The fourth ring has 15 strongholds within 10,496-12,032 blocks of the origin.The third ring has 10 strongholds within 7,424-8,960 blocks of the origin.The second ring has 6 strongholds within 4,352-5,888 blocks of the origin.


Because Bedrock Edition appears to begin stronghold generation at a spiraling staircase, it is rare to find no portal room in the stronghold. There appears to be an infinite amount of strongholds, even formerly capable of generating in the Far Lands. If it has to, a stronghold could generate perfectly fine above ground, in caves, and in canyons. Unlike most structures they appear to have no fixed set distance, which means that rarely they may overlap. In Bedrock Edition, strongholds generate randomly throughout the world. Canyons do not overwrite strongholds rather, a stronghold can occasionally be found exposed by a canyon. Most parts of the stronghold can be overwritten by caves, ocean monuments, ancient cities, mineshafts, fossils, amethyst geodes, and dungeons but it is rare for the end portal to be replaced, which would force a player to find one of the other strongholds, as a portal can be activated only with all 12 frame blocks present. Strongholds may generate at bedrock level, cutting the bedrock. Strongholds mostly generate underground and prefer to generate in biomes above sea level but generate underwater if necessary.
