An End Portal is a special structure in the game Minecraft that allows players to access the End dimension. This dimension is home to the Ender Dragon and various unique resources. To activate an End Portal, players must place Eye of Ender items into the portal frame, which consists of 12 portal frame blocks arranged in a rectangular shape. Once activated, the End Portal creates a shimmering surface that players can jump into to enter the End. Finding an End Portal typically involves exploring Strongholds, which are underground structures that can be located using Eye of Ender. The End Portal is essential for players seeking to defeat the Ender Dragon and complete the game.
