About Ruined Portals
Ruined Portals are naturally generated, incomplete Nether Portals found in both the Overworld and the Nether. Introduced in Minecraft 1.16 (Nether Update).
They are constructed mainly from Obsidian and Crying Obsidian, often with other blocks like Netherrack or Blackstone mixed in, sometimes covered by lava. Each portal generates with a chest containing loot, often including gold items, fire charges, obsidian, and flint & steel.
This finder shows the coordinates (X, Z) of the chunk where a Ruined Portal attempts to generate. The actual portal structure might be slightly offset within the chunk and can be above ground, underground, or underwater.
