See § Structure

A ruined portal is a structure resembling a damaged Nether portal, which generates in both the Nether and the Overworld. It contains some decoration and a loot chest around it.

Generation

Underside of a ruined portal

Ruined portals are the only structures that generate in more than one dimension; they generate in all biomes in both the Nether and the Overworld, except the deep dark. They can spawn underground, underwater, or exposed to the air. If they generate underground, they have air pockets around them. Natural terrain around ruined portals generates as netherrack. They also generate a mass of netherrack underneath them (including "stalactite"-like shapes, and this may contain blackstone deposits in the Nether). Giant ruined portals have 3 distinct designs, and normal ruined portals have 10 designs. When a ruined portal generates, it has a 5% chance to be a giant ruined portal, for about a 1.67% chance per giant portal design. This gives normal ruined portals a 95% chance, for a 9.5% chance per normal ruined portal design.​

Ruined portals that generate underground do so at Y-level from 15 to n−n2, where n is the highest block at the point of generation and n2 is the height of the ruined portal structure. This means the terrain is always higher than or level with the top of the structure. Some ruined portal variants are short enough to generate completely on the surface.

Ruined portals that generate in windswept hills generate at y-level from 70 to n−n2.

Ruined portals that generate partially buried do so at y-level n−n2, plus a random integer from 2 to 8. This means that the structure has 2 to 8 layers raised above the surface.

In the Nether, ruined portals with air pockets generate from Y-level 32 to 100. Ruined portals without air pockets have a 50% chance to spawn from Y-level 27 to 29, and a 50% chance to spawn from Y-level 29 to 100.

Many blocks in ruined portals are replaced upon generation. A ruined portal is in a cold biome if the temperature is less than 0.15.

Structure

Main article: /Structure

Ruined portals generate damaged portal frames composed of obsidian, sometimes along with crying obsidian, although Nether portals cannot be activated with crying obsidian in the frame.[1] Some frames generate flat on the ground, as if they toppled over. Others are free-standing separately, as if still being assembled/attached.

All ruined portals generate with a chest in Bedrock Edition, but in Java Edition, the chest may be replaced if terrain overrides it (often lava). Each chest contains various gold items and items used to build portals, such as obsidian and flint and steel.

Any ruined portal generated in the Overworld is surrounded with structures made of stone, stone bricks, and iron bars; in the Nether, it is surrounded by blackstone variants and chains.

There are 13 variants: 10 normal size portals and 3 giant portals in varying states of decay.

In Java Edition, ruined portals can be generated by the player by loading ruined_portal/portal_<1 to 10> or ruined_portal/giant_portal_<1 to 3> with a structure block. These ruined portals generate as they are stored, meaning they are not modified as detailed in the Generation section above. All portals generated this way create air pockets if generated in other blocks.

Overworld

Note that some blocks can be replaced with others (such as crying obsidian) upon generation. A full list can be seen below.

  1. The size of stacks (or for unstackable items, number) of this item on any given roll.
  2. The weight of this item relative to other items in the pool.
  3. The odds of finding any of this item in a single chest.
  4. The number of items expected per chest, averaged over a large number of chests.
  5. The average number of chests the player should expect to search to find any of this item.
  6. 'Nothing' does not refer to the chance of an empty chest. Instead, it refers to the chance that the random loot generator does not add any loot on a single roll.
  7. a b c d e f g h i All enchantments are equally probable, including treasure enchantments (except Soul Speed, Swift Sneak, and Wind Burst), and any level of the enchantment is equally probable.

Most ruined portal structures contain enough obsidian to make a complete portal, although in the smaller portals, there may not enough because each obsidian has a 15%‌ or 20%‌ chance to be replaced by crying obsidian.

History

October 8, 2010Notch responded to the idea of Nether portals being found in randomly generated ruins as having "its own technical issues" alongside the way for the player to create their own Nether portals.
Java Edition
1.1620w16aAdded ruined portals.
20w17aRuined portals now generate less frequently.
Badlands no longer generate ruined portals using the "mountain" type, thus making ruined portals spawn at normal frequency in badlands.
20w18aGolden apples are now less common in ruined portal loot chests, having their weight changed from 40 to 15.
1.21.525w02aLodestones can now generate in ruined portal loot chests.
Bedrock Edition
1.16.0beta 1.16.0.57Added ruined portals.
beta 1.16.0.59Changed ruined portals generating in the Nether to use blackstone instead of Nether bricks.
Ruined portal loot chests now roll 4-8 times instead of 4-6 to match Java.
1.16.100beta 1.16.100.54Ruined Portals now can generate with 4–12 glistering melons instead of only one.
1.21.60beta 1.21.60.25Lodestones can now generate in ruined portal loot chests.
