Phetchaburi province

Phetchaburi (, ) is one of the western provinces ("changwat") of Thailand.
Geography.
Phetchaburi is in the northern part of the Malay Peninsula. The Gulf of Thailand is to the east. Most of the province is a flat plain. The Kaeng Krachan National Park is Thailand's largest national park, covering nearly half of the province. It covers 3000 km2.
History.
Phetchaburi is an old royal city, dating back to the Mon of the 8th century. Later Khmer settled in the city, as can be seen by the prangs of Wat Kamphaeng Laeng.
In 1860, King Rama IV built a palace near the city of Phetchaburi, commonly known as "Khao Wang", but its official name is Phra Nakhon Khiri. Next to the palace the king built a tower for his astronomical observations. On a hill near the palace is the royal temple Wat Phra Kaeo.
