Wat Chanthattharam, locally known as Wat That, is situated atop That Hill, one of the most scenic and strategically significant viewpoints in Khanom District, Nakhon Si Thammarat Province. The temple holds remarkable historical and archaeological importance, as it enshrines a rare ancient coral pagoda, scarcely found anywhere else in Thailand.

The pagoda was constructed using natural coral stones collected from the sea, carefully carved and stacked into the elegant bell-shaped stupa (Phum Khao Bin) form. This extraordinary structure reflects the deep devotion and craftsmanship of ancient Buddhist communities. According to local legends, the pagoda is believed to be associated with the sacred pilgrimage route used during the construction of Phra Borommathat Chedi at Wat Phra Mahathat Woramahawihan in Nakhon Si Thammarat city.

The layered coral bricks remain remarkably intact, showcasing the wisdom and ingenuity of traditional artisans who skillfully utilized local marine resources. Perched on the hilltop, the pagoda also serves as a natural panoramic viewpoint, offering sweeping vistas of Thong Nian Bay and the turquoise waters of Khanom stretching to the horizon.

Cool sea breezes drifting up the hillside create a refreshing and tranquil atmosphere, allowing visitors to feel relaxed and spiritually uplifted. Within the temple grounds, several ancient Buddha images and sacred relics are enshrined, providing opportunities for worship and merit-making.

Access to the summit is facilitated by a well-maintained stairway adorned with a graceful Naga (mythical serpent) staircase, blending harmoniously with the lush green forest surroundings. Each step upward feels like a journey into a realm of serenity, reflection, and reverence, honoring the ancestors who preserved this cultural legacy.

The surrounding forest remains rich and ecologically diverse, home to birds and small wildlife that enhance the peaceful ambiance with natural sounds. The coral pagoda stands not only as an architectural monument but also as a symbol of impermanence and enduring faith, having withstood the passage of centuries with quiet dignity.

Visitors often prefer arriving in the early morning or late afternoon to avoid the heat and capture soft natural light for photography. From the hilltop, the sight of small fishing boats gliding across the sea offers a glimpse into the traditional coastal lifestyle of Khanom’s fishing communities.

Wat Chanthattharam is also a favored destination for those seeking meditation, spiritual retreat, and mindful relaxation amidst nature. The local community continues to uphold rituals and annual religious ceremonies, preserving the pagoda’s sacred significance. The visible textures of brain coral and staghorn coral fossils embedded in the pagoda walls are particularly fascinating for visitors interested in history and natural science.

A visit to Wat Chanthattharam is a harmonious blend of pilgrimage, cultural exploration, and scenic relaxation. Any journey to Khanom feels truly complete when enriched by the serenity and sacred charm of this remarkable hilltop temple.
