Naturally Generated Structure
End Portals are always located within Strongholds, in their own "Portal Room." These "Portal Rooms" are hidden among the maze of other rooms within a Stronghold. There is only one Portal room per Stronghold.
- The End Portal Frames with the Eyes of Ender have different Block IDs.
- The End Portal room contains a Silverfish Spawner.
- The End Portal room can also be hidden by the walls of a Stronghold, although this rarely ever happens.
