Phetchaburi's hill palace was built for King Mongkut, who laid the foundation stone of its main hall himself in July 1859, and was finished in 1860; he wanted a summer residence and an observatory, being a serious astronomer as well as a king. The complex is spread over the three peaks of a 95-metre hill that locals call Khao Wang, palace hill, and connected by paved paths through frangipani trees. On the western summit stands the residence itself, a low white group of halls in a mixed Thai and European manner, with an open observation platform. The central peak carries Phra That Chom Phet, a white chedi visible from most of the town below. A temple, Wat Phra Kaeo, sits on the eastern peak; the site has been a historical park since 1979, and two of the palace buildings house a branch of the National Museum. The views take in Phetchaburi's roofs, the river and the flat coast beyond.
The main sights
- The royal residence - white halls and an observation deck on the western peak.
- Phra That Chom Phet - the white chedi on the central summit.
- Wat Phra Kaeo Noi - the small temple crowning the eastern peak.
- The funicular - the short cable railway up the hillside from town.
When to go
November to February is dry and cooler, which matters here because the paths between peaks are steps in the open. Go in the first hours after opening. Phetchaburi works as a day trip from Bangkok or a stop on the way to Hua Hin, and the hill also holds an evening light festival in February.
What to expect
Macaques live on the hill and are aggressive around food and plastic bags; keep both out of sight. The funicular queues on weekends and the walking route up is steep and unshaded. Interiors are sparsely furnished and shoes come off repeatedly. The view is broad rather than dramatic, over a fairly ordinary provincial town.
Nearby
Phetchaburi's old temples and cave shrines, and the coast at Cha-am.
