This schematic was crafted in 1.8.7 and will work in 1.8.8 YOU CAN get it to work in 1.7.10 but be ready cause it will replace missing blocks from the versions with whatever it can. I tried it in my 1.7.10 server and it replaced missing blocks with oil. But I use industrialcraft. So yeah. 1.8.7 you wont have any issues. Not saying you would in 1.7.10. Just depends on what you have in your server. I am working on fixing the castle to work with 1.7.10 and will post it when im done.
BTW You will have to add your own mote. I used a lava mote
In my early days of playing Minecaft, this was one of my creations. Castle o Brien. It has lots of potential to make someone a really nice stronghold.
Check it out.
Copied and saved at ground level. It will sit perfectly in a flat world or mountains. This was copied from a desert region of my server.
Hope you enjoy it and I would love feedback from it.
