When you spawn on this seed, the first thing you’ll see is tall extreme hills and a large floating island. These hint at how grand this seed really is. Not far away (relatively speaking) there is also a woodland mansion, one of the biggest structures on Minecraft. Get ready for a big adventure. These may take you awhile to explore.
One of biggest new features in the 1.11 Minecraft update is the addition of another generated structure called a woodland mansion. These are huge houses with two to three floors, many rooms, and even a few hidden secrets. It’s not unusual for these to spawn 10,000+ blocks away from the spawn. That’s why having one only a 1,000 blocks away from the spawn is so great even though it sounds far.
