The Phra Nakhon Khiri historical park, locally known as Khao Wang ("the palace hill"), overlooks the city of Phetchaburi, approximately 130 kilometers southwest of Bangkok. Built atop a hill about a hundred meters high, this nineteenth-century royal complex comprises a summer palace, several temples and a monumental chedi, all dispersed across three peaks connected by footpaths and a cable car.

Why Visit Phra Nakhon Khiri

• A royal summer palace from 1860, commissioned by King Mongkut (Rama IV) himself.

• Hybrid architecture blending classical Thai, Chinese and European neoclassical styles.

• A 360° panorama over Phetchaburi and the coastal plains from the peaks.

• Three distinct complexes to explore: palace, royal temple and grand chedi.

• A frangipani forest inhabited by macaques, freely accessible around the buildings.

History of the Palace

Particularly attached to Phetchaburi province, King Mongkut (Rama IV) had the Phra Nakhon Khiri palace built in 1860 to serve as a summer residence and royal retreat. The sovereign, passionate about astronomy, deliberately chose this hilltop for its sky-observation qualities. His successor, King Chulalongkorn (Rama V), continued to stay there and also left his mark on the site.

The site was designated a historical park in 1979 and placed under the supervision of the Fine Arts Department. Today, the palace houses a national museum displaying the personal objects of both sovereigns, as well as a collection of ceramics brought back from Europe and Asia in the nineteenth century.

What to See on Site

The complex is spread across three peaks connected to one another. Allow 2 to 3 hours for a complete tour without rushing.

The Western Peak: The Royal Palace

This is where the residential buildings are concentrated, formerly secured by four corner forts and surrounded by quarters for servants and guards. The Phra Thi Nang Phet Phum Phirot throne hall is the palace's largest building: visitors can tour King Mongkut's personal quarters, including his bedroom, dressing room and dining room, preserved with their original furnishings.

The neighboring building, Phra Thi Nang Pramot Mahaisawan, housed the queen's chamber and provides a precise picture of the interior layout of a mid-nineteenth-century Thai royal residence.

Higher up, the Ho Chatchawan Wiang tower served as King Mongkut's astronomical observatory. Today it offers one of the park's most expansive viewpoints. Nearby, the Prasat Phra Thi Nang Wetchayan, a Khmer-style prang, recalls the cultic use of part of the site.

The Central Peak: Phra That Chom Phet

This peak is entirely occupied by the Phra That Chom Phet, a 40-meter-high white chedi visible from throughout the city. Its slender silhouette is the emblematic landmark of Khao Wang.

The Eastern Peak: Wat Phra Kaew

To the east stands the Wat Phra Kaew of Phetchaburi, a smaller version of the famous Emerald Buddha temple at Bangkok's Grand Palace. Built in pure classical Thai style, it served as a royal chapel during the king's visits.

Practical Information

• Access to the summit: paved paths from the base, or cable car at the foot of the eastern hill (recommended in extreme heat).

• Duration of visit: 2 to 3 hours for all three peaks.

• Opening hours: open daily during daytime hours, with the museum closing slightly earlier than the park. Check on arrival before heading up.

• Entrance fee: modest paid entry, with an additional fee for the cable car.

• Photography: prohibited inside palace buildings; permitted outdoors.

• Macaques: numerous and accustomed to visitors. Keep bags closed and food out of sight.

When to Visit

The best period runs from November to February, during the dry and cool season. Temperatures remain manageable for the uphill walk, and morning light highlights the white chedi and palace roofs. From March to May, midday heat can be challenging: favor an early morning or late afternoon visit. The rainy season (June to October) makes trails slippery but offers lush vegetation around the buildings.

How to Get There

Phetchaburi is approximately 2 to 2.5 hours from Bangkok by road. Several options:

• By train: Southern line from Hua Lamphong or Krung Thep Aphiwat station, getting off at Phetchaburi station.

• By minibus: regular departures from Bangkok's Southern Terminal (Sai Tai Mai).

• By private car or taxi: Route 35 then Route 4 (Phetkasem).

On site, the historical park sits on Khao Wang hill, immediately adjacent to Phetkasem Road. Tuk-tuks, songthaews and local taxis reach it in minutes from town. Renting a two-wheeler for the day remains a practical option for combining Khao Wang with other sites in the city.

Nearby

Phetchaburi often serves as a base for exploring a less-frequented Thailand. To extend your cultural journey, the Chao Sam Phraya National Museum in Ayutthaya complements the discovery of royal collections nicely. For nature lovers, the Elephant Haven sanctuary offers an ethical encounter with elephants, while mountain enthusiasts can venture further to Doi Phu Kha National Park or Doi Mae Salong mountain in the North.
