Some instructions for a castle me and some of my friends are working on in Minecraft.

The grid on the ground is to better measure the blocks and to help keep track of elevation. This tower has 11 blocks on each side at the base, while the walls take up 12 blocks in height each starting at the base (6 blocks in height per floor), plus an additional half block to a block and a half for the walls at the roof.

The pic size totaled to 960x960 pixels.
