Beyond the Lands is a time-tested texture pack for Minecraft PE, created specifically for those players who love realism. There are no humorous mobs or smooth blocks, this texture pack is concentrated on ancient buildings and medieval atmosphere. If you play the PC version of Minecraft, then you can try the Beyond the Lands original pack designed for computers.
One of the advantages is a sufficiently low brightness. You will get the impression that you really are in the 15th century during the reign of kings. Please note this is a ported version and there may be some errors.
