Khao Sam Roi Yot Ancient Sites

Introduction: The Prehistoric & Royal Sanctuary of Prachuap Khiri Khan

Situated within the towering limestone karst landscapes of Prachuap Khiri Khan Province, Khao Sam Roi Yot National Park is home to some of Western Thailand's most significant ancient sites, royal monuments, and archaeological discoveries. Spanning thousands of years of human activity, the park preserves a fascinating timeline ranging from 29,000-year-old Stone Age cave burials to 19th-century royal monuments.

Renowned globally for the iconic **Phraya Nakhon Cave** and its golden royal pavilion, the region's vast network of limestone caverns and coastal shelters has long served as sacred shrines, royal retreats, and prehistoric dwellings along the Gulf of Thailand.

Key Archaeological & Historical Sites

Khao Sam Roi Yot's historical highlights bridge deep prehistory with modern Thai royal heritage:

1. Phraya Nakhon Cave & Kuha Kharuhat Pavilion

The park's most famous attraction is a massive, two-chambered limestone cave featuring an open sinkhole ceiling that lets in beams of sunlight. Sitting inside the illuminated chamber is the **Kuha Kharuhat Pavilion**, a historic four-gabled wooden pavilion constructed in 1890 for King Chulalongkorn (Rama V). The cave walls also bear the carved signatures of King Rama V, King Rama VII, and King Rama IX.

2. Tham Din Cave (Prehistoric Burial Site)

A ground-breaking archaeological discovery site where researchers excavated the 29,000-year-old skeleton of a 6-to-8-year-old child (nicknamed "Pangpond"), making it the oldest human skeleton ever unearthed in Thailand. The burial site showed evidence of deliberate ritualistic traditions, with the body laid out and covered in red ocher and stones.

3. Prehistoric Rock Art Caves

Several limestone caves across the national park feature ancient red ocher rock paintings dating back over 3,000 years. These prehistoric artworks depict human figures wearing traditional accessories, hunters wielding bows and arrows, and wild animals native to the region, such as mountain serows.

4. Historic Coastal Fishing Villages

Traditional coastal settlements like **Bang Pu** and **Ban Khung Tanot** have operated along the park's bays for centuries. These historic villages preserve traditional wooden longtail boat fishing heritage, serving as the primary departure points for boat trips to Phraya Nakhon Cave.
