Luang Pho To, Wat Phanan Choeng, is 26 years older than Ayutthaya.

Wat Phanan Choeng Worawihan is a famous temple located in Khlong Suan Phlu Subdistrict, Ayutthaya Province. It is an ancient temple and one of the most important temples in Ayutthaya. In particular, Luang Pho To or Chao Pho Sam Pok Kong is a large Buddha statue in the Mara-Vijaya posture, which is considered the largest in Phra Nakhon Si Ayutthaya. Wat Phanan Choeng Worawihan has a long history. It was built before the establishment of Ayutthaya, but there is no clear evidence of who built it. According to the Northern Chronicles, it is said that King Sai Nam Phueng was the builder and gave the name Wat Chao Phra Nang Cheing. In the Luang Prasat Chronicles, it is also stated that the Buddha statue named Phra Chao Phanang Cheing was built in 1867, which was 26 years before King U Thong established Ayutthaya. The highlight of Wat Phanan Choeng Worawihan is Luang Pho To, a Buddha statue in the late U Thong art style in the Mara-Vijaya posture. It sits in a cross-legged position, with a lap width of 14 meters and a height of 19 meters. It is beautifully lacquered and gilded. In addition, Luang Pho To is one of the most respected Buddha images among the Chinese people. In Chinese, he is called Sam Po Kong, which is why many believers travel to pay homage.
