Phetchaburi, also known as Phetburi, is a town in central Thailand, capital of the Phetchaburi Province. It is approximately 160km south of Bangkok, at the northern end of the Thai Peninsula.
The Phetchaburi River runs through the middle of the city. The region is mostly flat, save for a hill (called Khao Wang) on the outskirts of town. The royal palace named Phra Nakhon Khiri and one of the many wats are on top of Khao Wang. The hill and town is the site of an annual festival, called the Phra Nakhon Khiri Fair. It lasts for eight days in early February and includes a sound and light show and classical Thai dance.
