Exit portal

The exit portal (also known as the end fountain) is a structure that enables the player to return to their spawn point, activated upon the defeat of the ender dragon.

Generation
The exit portal always generates at the coordinates  in the End biome, and is de-activated whenever an ender dragon fight is in progress. The y-level of the portal is determined by the height of the end terrain.

Structure
The exit portal looks similar to the end portal but differs in its design. Instead of a frame of end portal frame blocks, it has a 7-block wide bowl-shaped frame of bedrock, and a central pillar of bedrock with a torch on each side. A dragon egg generates atop the portal upon defeating the ender dragon for the first time.

There are 16 end stone blocks, one under each outer bedrock block, as well as four torches. If the blocks are removed, they regenerate when the ender dragon is defeated or respawned.

Behavior
The portal returns the player to their spawn point. The credits roll when a player enters a return portal for the first time.

If an entity other than a player goes through, like falling sand or thrown items, it is sent to the world spawn.

If a player dies above the portal (for example by flying into the bedrock column with enough momentum) the player goes through and player's items disappear.

Using custom world generation, if the end biome appears around the origin in the Overworld, the Nether, or a custom dimension, then the exit portal appears at 0,0 with the portal blocks in place. However, instead of taking the player to their spawn point, the portal takes the player to the End dimension.

Trivia

 * $$, if the player manages to break all of the end portal blocks in the exit portal, the entire structure regenerates after 5 seconds.
 * If all of the portal blocks have end crystals above (so the fire constantly eliminates the portal), this regeneration process repeats until a portal block successfully regenerates.
 * If an End Portal is built in Creative mode in The End, then it also acts as an Exit Portal.
