Earth Tower - north
In addition to these built an the vaulted passage into the ravine - under the Earth Tower.

Air Tower - east
There will become even some flying vehicle in the air - maybe an air ports.

Fire Tower - south
There will be even more construction works around the plinth of this tower deep underground.

Water Tower - west
Its plinth stands in the water. I plan here to build a harbor.

Special thanks to Xanoxian for inspiration.
