Phra Nakhon Khiri Historical Park

Phra Nakhon Khiri Historical Park, commonly known as Khao Wang, is a hilltop palace complex in Khlong Krachaeng, Mueang Phetchaburi, Phetchaburi Province. Built between 1859 and 1860 as a summer palace for King Mongkut (Rama IV), it occupies three peaks overlooking Phetchaburi town. The site combines Thai, Western neoclassical and Chinese architectural styles and includes palaces, temples, observatory and museums, now preserved as a historical park.

Visitors can expect a hilltop complex spread across three peaks accessed by cable car or a steep walking path. The site includes restored palace buildings, halls and museums displaying royal artifacts, Wat Phra Kaeo Noi (Wat Phra Kaew Noi) with its white chedi, an old observatory tower, fortified walls and landscaped grounds. Panoramic views over Phetchaburi town, rice fields and coastline are available from viewpoints. Monkeys inhabit the hill and grounds.
