Seed ID: 4852754096646050338
This seed will spawn you near to an underground stronghold, with an end portal inside it. It was found by ZachZoom.
Head behind the spawnpoint, into the jungle. You will see a large pool of water, and behind that there will be two smaller pools. The stronghold is directly beneath this point.
If you dig at these exact coordinates:
x: -482 z: 599
This seed works for minecraft version: 1.2, 1.3, 1.4, 1.5
You will dig yourself right into the room that contains the end portal. Be warned though, there will be a mob spawner next to the portal, and the door to the rest of the stronghold is locked.
Wow… This actually worked. You should include how far to go down
works in 1.8.8 on my mac. stronghold is at the said cord. Library is at -490/37/528
In update 1.9, using a PC,
Face the Birch Tree at Coordinates: -1033/66/1102
Then dig straight down, then you will be presented with the End Portal.
