Omashu Royal Palace

The Omashu Royal Palace was home to the city's king prior to the city's annexation by the Fire Nation, and was located at the top of the Omashu's central mountain peak. It was a palace consisting entirely of Earthbending-operated doors and would be impossible for anyone but an Earthbender to get through it. The palce also contained an Earthbending Arena, a location with a waterfall where Bumi tests people's skill, and a place where he keeps his pet Flopsie.

Following the successful invasion, the palace was destroyed by the Fire Nation government and replaced by a statue of Fire Lord Ozai, in commemoration of the renaming of the city to "New Ozai". The Fire Nation governor currently resides in a separate Governor's Palace, constructed in the traditional style of the Fire Nation mainland. It had numerous chambers, a throne room, bedrooms, barracks, and servant's quarters, presumably, and also prison cells.

The palace was presumed to be rebuilt after Bumi's liberation of Omashu.
