Seed: Infinite Mineshafts and Woodland Mansion

This is an excellent seed for Minecraft Pocket Edition that allows you to find a huge Woodland Mansion along with endless abandoned mineshafts beneath it.

How to Find the Infinite Mineshafts?

The spawn point is located around 200 blocks away from the Woodland Mansion. Simply walk forward and you will eventually reach it.

Somewhere near the mansion, you will find a giant mushroom.

Dig down beneath it to reach the infinite mineshafts (X: 345, Y: 65, Z: 302).

The mineshafts are truly massive, and even if you teleport to X: 10000, Y: 13, Z: 10000, you will still see abandoned mineshafts generating there.

You can also find a dungeon inside the mineshafts at the coordinates: X: 400, Y: 13, Z: 285.
