Khao Wang is a range of low hills with 3 big peaks, the highest is 95 metres. When the king Rama IV had the palace built on the western peak, he also had a new white stupa built to shelter the old chedi on the middle peak. The new chedi enshrining the relic was called Phra That Chomphet. He also bilt Wat Kaeo to the New palace’s temple on the eastern peak. The stucco pattern on the chapel’s gable was the Royal Crown, the emblem of King Rama IV. Behind the chapel, there is a marble stupa in greenish. Its unique construction is being sculptured at Ko Sichang and brought to be erected here.
The buildings on Khao Wang were constructed in western style which had just come in fashion for the court at the time and also in Chinese style which had been fashionable since King Rama III. The palace is admirably unique monument of that period.
