The UNESCO World Heritage site is also the world's biggest and best-preserved royal compound featuring wooden buildings.

Its current role as the Palace Museum, which opened to the public in 1925, enables its rich art and history to enthrall visitors from around the world.

The set of four stamps depict iconic structures, including the stone bridges across the Golden River; Zhonghe Dian, or the Hall of Central Harmony; and Qianqing Gong, or the Palace of Heavenly Purity.

These experienced severe damage in several fires and reconstructions.

The stamps also feature Qianqiu Ting, or the Pavilion of Immortality, in the Imperial Garden.
