The Main Bell-shaped Chedi, also known as the Phra Borommathat Chedi, features classic bell-shaped architecture with its most striking feature being the golden spire, which is covered in genuine gold. According to longstanding beliefs and oral traditions, the entire structure is said to be filled with precious gold ornaments and valuable offerings extending all the way to the tip of the stupa. These offerings were made by devoted Buddhists as acts of reverence to the Lord Buddha, with the aspiration of attaining Nirvana.
The phrase "Phra That Thongkham" (Golden Relic) found in the provincial motto of Nakhon Si Thammarat refers to this golden spire of the Phra Borommathat Chedi. In addition to its beauty, the chedi is renowned for its sanctity and spiritual significance, attracting worshippers and visitors from all over who come to pay homage and seek blessings.
