My last project i ever did on minecraft. My epic attempt of combining my minecraft building techniques to a functional, offensive, and defensive base.

from the bottom up:
Underground there is many combination locks, on to get into the commanders room, and the other to open and active the detonation room. There are also some basic living quarters that I'll update when i may be able to get this into a multiplayer server.

First floor has eight melee points, four projecting from the sides, with four "feet" that you can only get into from the tunnel below it. Beside the side points are two arrow launchers, powered by a redstone engine on each side, that makes them machine guns the walls have a outer coating of cloth, to make it flamable, with a tall wall of sand sandwiched between two layers of stone, so it can take lots of abuse.

The second story is the tactical defense room. it has controls to open lava or water gates. This can aid in defeating enemies, or create a quick wall if needed.

The third story is the archers balcony/observatory. You can get a good view of the battle field here, walks on the ledge to fire arrows, or activate another set of four engines, with eight dispensers total.

The fourth layer is turrets. 4 available cannons that are easy to load, but the outside is unlit, and can produce monsters here, so be careful! This is also the only level with exposed red wire, it would be too difficult to hide it, and i was running out of space.

Firth floor is the cannon sights. the only thing on the floor is the top window view , and the detonate switch for the cannons.

The very top is a lit dome, able to grow produce here(I havn't tried tree yet,
but there should be enough space for a few small trees.) It has flowing water, and enclosed glass ceiling for sunlight as well.

At the very top is the detonation plug, which is where the signal from the lowest part of the basement activates the 1000+ TNT core. i HAVE activated it before. It crashed the game, but when i came back, there was only a giant crater, and the four obsidian tubes that are the cannons. The only safe spot was the commanders room, which was very surprising for me.I built a secret safe room behind that room, because i believed it was going to be destroyed!

I am looking for a server to place this in, perhaps in the heart of a city, or on top of a underground vault. I am talking to some one who may plant this into their server.

I first built this as part of a "team castle" where two teams would play, on trying to break it down using their own cannons and TNT, while the other team operates this base. but since this building doesn't have a "front" i didn't know where to place the oppressing teams camp.

I have edited the picture by blacking out the background, which should make this acceptable to upload!
