You’ve spent hours mining. Your diamond pickaxe is almost toast, and your inventory is a chaotic mess of cobblestone, string, and raw gold. Then, you hear it—that low, pulsing hum that vibrates through the stone walls of the stronghold. You break through a final layer of mossy stone bricks and there it is. But if you’re expecting a shimmering blue pool like the ones that take you to the Nether, you're in for a surprise.
Basically, an End Portal doesn't look like any other block in the game. It’s weird. It’s haunting. Honestly, the first time I saw one, I thought my graphics card was glitching.
The Physical Structure of the Portal Frame
When you walk into that specific room in the stronghold—usually guarded by a silverfish spawner that you should probably break immediately—you’ll see a 5x5 horizontal square. Well, it's a square with the corners missing. The actual frame consists of 12 individual End Portal Frame blocks.
These blocks are unique. They have a yellowish, bone-like texture on the sides, decorated with a green, ornate pattern that looks vaguely like an eye or an ancient rune. The top of the frame is flat and slightly recessed, featuring a circular indent. This is where the Eye of Ender goes. If you find a portal naturally, some of these eyes might already be filled in, but usually, you'll need to bring a handful of your own to finish the job.
What’s wild is that these frame blocks are technically "unbreakable" in Survival mode. You can't mine them and take them home to build a cool basement entrance. They are fixed in space, tethered to the world generation of that specific stronghold.

That Eerie Black Void
Once you pop the final Eye of Ender into the last frame, the center of the square transforms. It’s no longer empty air.
What does an End Portal look like once it's activated? It looks like a window into deep space. The center fills with a pitch-black substance known as the End Portal Effect. It isn't just a flat black texture, though. If you move your camera, the stars inside the portal seem to move at a different depth, creating a parallax effect. It’s like looking into an infinite, star-filled abyss that exists "underneath" the world.
There are no swirls. No purple ripples. Just a cold, silent void.
Falling into it is instantaneous. Unlike the Nether portal, where you have to stand in the purple haze for a few seconds while the screen wobbles, the End Portal is a "touch it and you're gone" situation. You hit that black surface and the loading screen triggers immediately.
Why the Design Matters for Gameplay
Minecraft’s lead developers, including Jens "Jeb" Bergensten, have often leaned into a "liminal" aesthetic for the End. The portal's look is the first hint that you are leaving the physical, blocky reality of the Overworld for something... different.
The color palette is intentional. The pale, sickly cream of the frame blocks matches the End Stone you’re about to encounter. The green accents on the frames match the color of the Eyes of Ender and the particles emitted by Endermen. It’s cohesive design, even if it feels alien.
Spotting the "Fake" Portals
Sometimes, world generation goes sideways. You might find a stronghold where a ravine or a dungeon has cut right through the portal room. In these cases, what an End Portal looks like is "broken."
If even one of those 12 frame blocks is missing or destroyed by a stray piece of generation code, the portal cannot be activated. You can place all the eyes you want; that space-void isn't appearing. This is why seasoned speedrunners like Dream or Benex often have a backup plan. If you find a "dud" portal, you genuinely have to trek thousands of blocks to find a completely different stronghold. It sucks, but it's part of the RNG (Random Number Generation) grind.
Visual Cues and Hidden Details
If you look really closely at the activated portal texture—the "Gateway" or "End Portal" block—you'll notice it’s actually a specialized shader. It’s the same visual effect used for the End Gateways (the tiny 1x1 portals that spawn after you kill the Dragon).
- Light Level: The portal itself actually emits a light level of 15. It's one of the brightest objects in the game.
- Transparency: From underneath, the portal is invisible. If you dig under the portal room and look up, you won’t see the starry void. You’ll just see the bottom of the frame blocks.
- Sound: It makes a constant, low-frequency drone. It’s a sound file titled
portal.travelorportal.triggerin the game code, and it’s designed to be slightly unsettling.
There’s also a weird quirk with how it interacts with other items. If you throw an item into the portal, it doesn't just sit on top. It vanishes. It’s sent to the End spawn platform immediately. This has led to some pretty creative redstone builds involving item transport across dimensions, though most people just use it to chuck their spare dirt into the void.
The Difference Between Creative and Survival Portals
In Creative mode, you can actually build your own portal. But there's a catch. If you just place the blocks in a square, it probably won't work.
The frames have an "orientation." When you place an End Portal Frame, the "front" of the block (the side with the little decorative bits) must face the center of the portal. If you stand in the middle of the hole and place the blocks around you, they will all face inward correctly. If you stand outside and build it like a fence, the portal won't activate.
It still looks the same—creamy blocks, green runes—but it remains "hollow" until those frames are placed with the right directional data.
Summary of Visual Identifiers
- Frame Color: Pale beige/yellow (End Stone color).
- Frame Pattern: Green, eye-shaped runes on top.
- Activated Center: Deep black with "moving" white/grey stars.
- Shape: 3x3 interior space, 5x5 exterior (minus corners).
- Environment: Almost always found over a pool of lava in a stone-brick room.
Practical Steps for Your Next Trek
Finding the portal is one thing, but seeing it activated is another. If you're heading out to find what an End Portal looks like in your own world, keep these specific tips in mind to avoid a wasted trip:
- Stock up on at least 12 Eyes of Ender. While some frames might be pre-filled, it is extremely rare (a one-in-a-trillion chance) to find a fully completed portal. Most have zero to three eyes already in place.
- Listen for the Silverfish. If you hear that annoying scratching sound, you are getting very close to the portal room.
- Bring a Water Bucket. The portal sits directly over a pool of lava. One wrong move while placing an Eye of Ender and your gear is toast. Cover that lava with obsidian or cobblestone before you start decorating the frame.
- Check the Alignment. If you are in Creative mode and your portal isn't turning into a starry void, break the frames and replace them while standing in the very center of the 3x3 square.
- Set a Spawn Point. Place a bed in the room adjacent to the portal (but not in the portal room itself, as silverfish might break it). If the Ender Dragon knocks you off the island, you’ll want to be right back at the portal entrance rather than 2,000 blocks away at your main base.
Once those eyes are in and that black void appears, take a second to look at the parallax effect. It’s one of the most unique visual assets in Minecraft’s decade-long history. After that, take the leap. The credits won't roll until you've seen what's on the other side.
