The Sanctuary of Truth, known as Prasat Sut Ja-Tum in Thai, is a unique religious and architectural masterpiece located in Pattaya, Thailand. It is a temple-like structure crafted entirely out of wood and is renowned for its intricate carvings and ornate design.

The Sanctuary of Truth was conceptualized by a Thai businessman named Lek Viriyaphant with the vision of creating a monument that celebrates traditional Thai craftsmanship and spiritual beliefs. Construction of the sanctuary began in 1981 and is an ongoing project that aims to reflect the ancient philosophies and wisdom of Eastern art, culture, and religion.

The entire structure is made of teak wood, with no metal nails or modern construction techniques used in its assembly. Skilled craftsmen meticulously carve every intricate detail by hand, resulting in a breathtaking display of architectural artistry. The carvings depict various mythological and spiritual elements, including deities, celestial beings, mythical creatures, and scenes from Hindu and Buddhist scriptures.

The Sanctuary of Truth stands at a height of over 100 meters (328 feet) and covers an area of about two rai (approximately 0.8 acres). Its towering spires, grand entrance, and elaborate interior make it an impressive sight to behold. The temple's design is influenced by ancient Khmer, Indian, and Thai architectural styles, combining elements of different cultures to create a harmonious and spiritually significant structure.

The sanctuary is not just a tourist attraction but also serves as a place of worship. Visitors can explore the ornate halls, walkways, and open-air spaces, admiring the stunning craftsmanship and immersing themselves in the spiritual ambiance. The sanctuary also hosts daily cultural performances, including traditional Thai dances and music, adding to the cultural experience.

The Sanctuary of Truth is situated on the scenic coastline of Pattaya, providing picturesque views of the Gulf of Thailand. The surrounding area offers additional attractions such as beautiful beaches, water activities, and other cultural and entertainment venues.
