Phetchaburi is a town (thesaban mueang) in central Thailand, capital of the Phetchaburi Province. In Thai, Phetchaburi means city of diamonds (buri meaning city in sanskrit). It is approximately 160km south of Bangkok, at the northern end of the Thai Peninsula. As of 2005, the town has a population of 26,181 and covers the two tambon Tha Rap and Khlong Krachaeng.
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.
The official city flower is the leelowadee flower or frangipani.
Phetchaburi is known for its traditional Thai desserts. The most well-known is a custard dessert called Khanom Mor Gaeng. Other popular desserts include Portuguese-influenced thong yip, thong yod, and foi thong
