Rammed Earth Wall

 is one of the buildings in Oriental Empires.

Description
The sticky yellow earth of China can be placed in a frame and repeatedly pounded with a special stick until it becomes extremely hard. While there is some technique in this, the real challenge is to organize the thousands of workers needed to create a suitable wall around a large city.

Effects

 * Rammed Earth Walls are an upgrade over a simple wooden palisade in that only the gates are flammable.
