The second largest city in the Earth Kingdom and the capital of one of its provinces. The gates of this bustling metropolis are guarded by an army of earthbenders. This city is also well-known for its famous delivery system powered by a combination of earthbending and gravity. The tall mountain peak on which Omashu was founded rises high out of a deep chasm. Being built on this mountain provides the city with one of its best defenses; the only way to reach the gates of Omashu is across a long narrow bridge of stone that spans the sheer gorge.
