This summer palace was built by King Rama IV in 1860. It was named Phra Nakhon Khiri Palace, but the folk usually call it Khao Wang.
This covers a hilly area with an old palace and historical temples in the vicinity of the town.
It consists of royal halls, temples and groups of buildings, constructed mostly in harmonious Thai, Western neoclassic and Chinese architectural styles.
The Phra Nakhon Khiri Museum on the western hilltop exhibits some royal paraphernalia of King Rama IV and King Rama V, decorative sculptures and ceramics from China, Japan and Europe. To reach the hilltop, one can either walk or take a cable car.
