Stronghold

Strongholds are generated structures added in Update 0.9.0. Unlike most structures, Strongholds are intended to be difficult to locate through conventional means, providing almost no outward indication to exposed areas unless exposed through the surface or through water. Strongholds are the rarest Generated Structure.

Layout

 * Strongholds vary in size but are generally large and complex like a maze, containing multiple rooms, corridors, libraries, stairwells, doors, and other features.
 * They mainly consist of Stone Bricks, Mossy Stone Bricks, and Cracked Stone Bricks.
 * Strongholds are lit by enough torches to provide visibility in most areas, though not enough to suppress mob spawns.
 * In the Portal Room there is a Silverfish spawner.

Loot
It is possible to get loot from chests present in Strongholds. They are:
 * Diamonds
 * Apples
 * Ink Sacs
 * Armor
 * Iron Ingots
 * Emeralds
 * Gold Ingots
 * Bread
 * Paper
 * Books
 * Coal
 * Iron Swords
 * String
 * Gunpowder
 * Saddles (Upcoming)

Trivia

 * Very rarely, they will intersect a mineshaft and/or a dungeon.
 * Strongholds contain an End Portal, but it does not yet function in Pocket Edition.
 * Strongholds are the only place where Silverfish spawners are found.
 * Eye of Enders naturally spawn on the End Portal Frame, but they cannot be obtained separately as there are no Ender Pearls.
 * In PC, the easiest way to locate a Stronghold is to throw an Eye of Ender into the air.
 * Unfortunately, there is no Eye of Ender yet in MCPE.


 * Most of the blocks in the entire Stronghold are actually Silverfish Stone.
