Hall of the Supreme Principle

This residence was built in 1420 and was originally called the "Palace of Endlessness" (未央宫; Wèiyānggōng).

As his father was born here, the Jiajing Emperor renamed it the "Palace of Endless Good Omens" (启祥宫; Qǐxiánggōng) in 1535.

The main hall has a gabled roof covered with yellow glazed tiles like most palaces in Forbidden City.

[2] The beams are decorated with Suzhou style paintings, golden dragons, and phoenixes.

The walls are intricately decorated with medallions of phoenixes sitting on the mountain, atypical for other palaces.
