Wat Chulamani is an ancient temple on the banks of the Amphawa Canal, which connects to the Khlong Phi Lok. It was built in the late Ayutthaya period. Originally named Wat Mae Chao Thip, it was constructed during the reign of King Prasat Thong. It is believed to have been built between 2172 and 2190. According to tradition, Thao Kaew Pluek (Noi), one of the daughters of Than Phlai, the head of the Bang Chang market, was responsible for collecting taxes and duties at the market and was the matriarch of the Bang Chang royal family.

Wat Chulamani experienced its golden age under the second abbot, Phra Athikarn Niam. He founded a school there where Thai and Khmer scriptures were taught. After his death around 2459, the temple was almost deserted. With only a few monks remaining, it fell into disrepair and largely became a ruin. The district chief of Pak Ngam (present-day Bang Chang) wishes to ask Phra Ajarn Chaem Solos, a young monk from Bang Kaphom Temple, to take over the leadership of the temple and lead it to renewed prosperity.

There are four statues of Thao Wessuwan, each with a different meaning and different beliefs.

Phrama Suthi Thep, a golden figure, is said to bless luck, career and money (the first statue of the temple).

Chatumharaj, a green and black figure, is said to bestow blessings and provide protection as well as warding off evil in life.

Thepbut Suthi Thep, a golden figure, is said to bestow blessings upon people so that their wishes, their lives, and their partners may be fulfilled.

The human being, a human figure, is meant to bestow blessings upon people so that they are successful in life and everything they do goes smoothly.

Wat Chulamani is located in Khlong Wat Chulamani, Village No. 7, Bang Chang Subdistrict, Amphawa District, Samut Songkhram Province.
