Phra Thinang Khuha Kharuehat

Phra Thinang Khuha Kharuehat is a royal throne hall standing on a raised platform within a limestone cave, featuring traditional Thai architectural elements. The pavilion relies on natural ceiling openings for light and combines ornate decorations with the raw cave structure.

The pavilion was commissioned by King Rama V in 1890 during his exploration of the coastal region and became the first royal structure built inside a natural cave. This construction marked a turning point in royal patronage as the crown engaged directly with the kingdom's landscape.

The structure merges royal design with a natural cave setting, revealing how the monarchy engaged with the landscape. Sunlight filtering through rock openings above creates a spiritual space where architecture and nature coexist.

Reaching the pavilion requires climbing about 430 meters (1,400 feet) through the cave system, so sturdy footwear is recommended. The ascent can be done in stages, and visitors should allow time for breaks to enjoy the surroundings.

The construction required the work of around 200 craftsmen from Bangkok who transported materials through the cave and worked under an experienced engineer's direction. This massive undertaking reveals the great effort the crown invested to create a refined structure in such a remote location.
