End portal

An End portal is a naturally-occurring generated structure that is used to travel into the End. It can only be found in the portal room of a stronghold.

In Survival mode, the player must venture to a stronghold to activate a pre-existing End portal, as End portal frame blocks cannot be obtained naturally. The portal is activated when an eye of ender has been placed in each of the End portal frame blocks, generating 9 End portal blocks within the structure. Eyes of ender cannot be removed from End portal frames.

In Creative mode, the player can construct an End portal by placing 12 End portal frames in a ring enclosing an open 3×3 square and placing an eye of ender in each one. In order to activate, the End portal frames must be oriented correctly; the front face of each portal block must be pointed inward toward the 3×3 portal area. This can be achieved by the player standing in the center of the portal area and rotating to place the frames in a ring around them.
