Minecraft wiki entry for Construction, associated text: This is the best choice if you wish to create a permanent base. This consists of a large fortified wall with an overhang to keep spiders out, as well as a wet or dry moat (optional). This will surround your entire settlement. This means your farms, houses and any other buildings you have will be protected. You may also wish to build a secondary fortification inside as well as a real-world castle (see topic below), just in case of a breach. In addition, you will want to build guard towers in each corner of the compound. This is to help keep your walls clean of mobs. These towers, if possible, should protrude from the corners so that you can clearly see and shoot anything near your wall. Be able to do this for the entire length of the wall to the next corner, or minimally to the halfway point between the two towers. This type of building is recommended for a player with large amounts of resources at their disposal.
