I made the walls surrounding the world. All of the other elements are parts of other builds which can be found on planetminecraft in the credits below (send me a notice if you want your build to be removed or if I may have forgot a build to credit).

The invincible district walls has one goal, to protect its citizens from (titans) threats. The elements composing it are mostly modular: the principal gate, the turret wall, normal wall, rounding bridge, wall corners. What is fun about the walls is that you can make it any shape you want (of course you need a large world for better and cleaner curves).

View it from your own eyes at play.govmc.net in the /warp Exchangis.
