The Huay Mongkol Temple houses the world's largest statue of Luang Pho Thuat. It was originally called "Wat Huai Khot" and was located in the Ban Huai Khot subdistrict, Thap Tai subdistrict, Hua Hin district, Prachuap Khiri Khan. Later, the king renamed the temple, from Huai Khot to Huai Mongkhon.

When he arrived at this temple, the plan was to build a new road—transforming a dirt track into a paved road—and name it after the temple. Luang Por Thuat, a large Buddha statue with a shoulder width of 9.9 meters, a height of 11.5 meters, and a three-story base. The first story is 70 meters wide and 70 meters long, rising majestically against the horizon. Amidst the temple's stillness, one can sense its aura emanating from it, spreading to the worshippers and conveying its teachings, which were left for future generations to preserve.

This place is very popular with Thais from all over the country who come to pay their respects to Luang Por Thuad and ask for blessings such as happiness, health, prosperity and contentment.

Next to the enormous statue stands a large wooden elephant. Villagers walk in a circle beneath the elephant's belly to ask for good luck. The area also features a Buddhist temple, an equestrian statue of King Taksin the Great, and a shop selling Buddhist amulets.
