Pra Somdej Wat Bang Khun Phrom: A Priceless Legacy of Buddhist Art and the Legend of Faith
Pra Somdej of Wat Bang Khun Phrom is regarded as a preeminent amulet, long cherished by devotees and connoisseurs of Thai sacred objects. It embodies profound historical significance, sanctity, and artistic beauty, expressed through its unique material composition and archetypal forms. The study of Pra Somdej from Wat Bang Khun Phrom is not merely an exploration of a religious artifact, but also an examination of Thai historical consciousness, belief systems, and ancestral wisdom as transmitted through masterful Buddhist artistry.
History and Legend of Wat Bang Khun Phrom
Wat Bang Khun Phrom was originally established during the late Ayutthaya period and was formerly known as “Wat Klang Nam” or “Wat Khlong Bang Khun Phrom,” reflecting its geographic setting—surrounded by waterways, giving it the appearance of an island amid water. During the reign of King Rama III of the Rattanakosin period, the temple underwent a comprehensive restoration under royal patronage and was officially renamed Wat Bang Khun Phrom.
Somdej Pra Phutthachan (To Phrommarangsi), commonly referred to by the laity as “Luang Pho To” or “Somdej To” of Wat Rakhang Kositaram, held a deep spiritual connection to this temple. It is widely believed, through oral tradition, that he once spent a monastic retreat at Wat Bang Khun Phrom and crafted sacred amulets which were then enshrined within the temple’s principal stupa. These amulets later came to be recognized as the revered Pra Somdej Wat Bang Khun Phrom.
Somdej Pra Phutthachan (To Phrommarangsi) and Pra Somdej
Born in the reign of King Rama I in the year 1788 (B.E. 2331), Somdej To was a venerable monk of great erudition and reputed supernatural power. He was renowned for both his scholarly prowess and meditative discipline. His words were believed to hold mystical potency, and he possessed exceptional skill in the formulation of sacred amulets.
He is credited with crafting amulets for three principal temples:
-
Wat Rakhang Kositaram (his monastic residence)
-
Wat Intharavihara (Wat Satu)
-
Wat Bang Khun Phrom
Historical evidence and oral testimony from village elders support the assertion that Somdej To had a meaningful affiliation with Wat Bang Khun Phrom and that he enshrined amulets within its stupa. Scholars of Thai amulets generally agree that these amulets were likely created between 1846 and 1868 (B.E. 2389–2411), which corresponds to the latter period of Somdej To’s life.
The Discovery of the Wat Bang Khun Phrom Stupa Cache
The discovery of the sacred Pra Somdej amulets at Wat Bang Khun Phrom occurred as a consequence of three major floods in Bangkok, each of which significantly impacted the structural integrity of the temple:
-
The Main Stupa Cache (Old Cache)
In 1901 (B.E. 2444), following a massive flood, the base of the main stupa subsided and cracked. During restoration efforts by monks and local residents, a large quantity of amulets was unearthed beneath the stupa’s foundation. These early Pra Somdej amulets exhibited a weathered metallic texture and were limited in number. Today, they are regarded as highly valuable due to their antiquity and artistic authenticity. -
The Small Stupa Cache (New Cache)
In 1957 (B.E. 2500), another major flood led to the structural collapse of a smaller stupa. Water seeped into the cracks, prompting the then-abbot, Pra Kru Palat Sampipattanawiriyacharn (Luang Pho Phon), to order its dismantling and restoration. This event led to the discovery of approximately 84,000 amulets—now famously referred to as the “2500 Batch.” These amulets form the foundation of the widespread contemporary collection of Pra Somdej Wat Bang Khun Phrom. -
The 1983 Flood
A third inundation in 1983 (B.E. 2526) necessitated further repairs. Although no additional amulets were found, this restoration occasioned a more methodical documentation and scholarly study of the amulets.
Sacred Composition and Consecration Rituals
The sacred composition (known as muan sarn) of Pra Somdej Wat Bang Khun Phrom is believed to have been a closely guarded formula devised by Somdej To himself. Expert analyses suggest the primary constituents included:
-
Powder from the Bodhi tree (Sri Maha Bodhi) soil in India
-
Ground palm leaf manuscripts used in sacred scripture
-
Animal bone dust—particularly elephant ivory—for structural integrity
-
Cremated bone ash from ancestors, believed to enhance spiritual potency
-
A mixture of 108 traditional Thai herbs (wan 108)
-
Sesame oil, used as a binding agent
-
Honey, also used as a binding agent
-
White clay (din sor phong), the primary filler material
According to ancient scriptures, Somdej To meticulously prepared these materials himself, selecting only the most sanctified substances. The amulets underwent elaborate Buddhist consecration rituals, including prolonged chanting and meditative empowerment. Some accounts state the consecration lasted precisely three years, three months, and three days.
The result was a durable, fine-grained texture that resists crumbling even when submerged in water. The amulets exude a subtle herbal aroma—an authenticating feature often cited by experts.

Impact of Floods on the Amulets
Each of the three major floods left unique marks on the amulets:
-
1901 Flood – Resulted in discovery of the earliest batch. Prolonged submersion caused water erosion, leaving “Chediyan” striations—valued markers of authenticity.
-
1957 Flood – Led to the release of the large 2500 Batch. Water interaction created blue-green chemical spots known as “blue dots” (chut fa)—distinctive of genuine amulets.
-
1983 Flood – Did not yield new amulets, but prompted scholarly preservation and cataloging of extant artifacts.

Phenomena of “Blue Dots” and “Chediyan”
“Blue Dots” are chemical formations of copper carbonate resulting from long-term exposure to moisture and air. This phenomenon, confirmed through scientific analysis by Professor Dr. Tharapong Wititsarn of Chulalongkorn University, is difficult to replicate artificially.
“Chediyan” are striated erosional patterns formed by water seepage in the old cache amulets, creating ripple-like impressions reminiscent of draped fabric.
