Phetchaburi’s most well-known landmark, the locally known as Khao Wang (Palace Hill), is located on the three peaks of 95-meter high verdant hill, in the city. It was built under the royal command of King Rama IV to become his summer palace that finished in 1860. The whole compound is comprised of royal halls, palaces, temples and other buildings which were elegantly constructed in a well-balanced of Thai, neoclassical Western and Chinese architectural styles.
