Phetchaburi has a long and rich history, which is reflected in the town's art and architecture. Originally, a Mon city, it fell to the Khmer Empire in the 12th century and was later part of the Thai Sukhothai and Ayutthaya kingdoms. Situated beside a river, the town is overlooked by Phra Nakhon Khiri ("Sacred City Mountain"), the neoclassical palace complex built by King Mongkut. Around the foot of the hill and in town are a number of interesting temples, one with a massive prang (Khmer-style spire), one with a beautiful wooden scripture hall in a pond, and several with Ayutthaya period murals.
Phra Nakhon Khiri: an extensive historical park (locally known as Khao Wang) with a museum, temple, chedi, prang, and a lot of monkeys.
