During the reign of King Rama V, Luang Pu Eiam, also known as Phra Phawana Koson Thera, the abbot of Wat Nang, was very famous. The abbot told us, “Wat Nang may not be particularly famous or beautiful, but Luang Pu Eiam amulets from Wat Nang are highly sought after in the amulet market. Their price never drops. A slightly less attractive specimen costs hundreds of thousands, while a truly good one costs millions. Ask any amulet expert.” According to the stories told by elders in the community, the term “Bang Chang Suan Nok, Bangkok Suan Nai” referred to two areas: the orchards and farms in the Bang Khun Thian area since the early Rattanakosin period, and the orchards of Bang Chang-Amphawa in Samut Songkhram province.

Wat Nang is one of the oldest temples in this area. The temples in this region are collectively known as "Wat Sam Phi Nong," which includes Wat Nang Ratchaworawihan, Wat Nang Nong Worawihan, and Wat Ratcha Orosaram Ratchaworawihan. Wat Sala Khruen is also located here. Wat Nang Nong Worawihan and Wat Ratcha Orosaram Ratchaworawihan were renovated during the reign of King Rama III, resulting in much of the artwork in these temples being of Chinese origin. Chinese tiles adorn the gables of the chapels and temples. King Rama III's mother had Wat Nang renovated, giving it a more pronounced Thai style than Wat Nang Nong and Wat Ratcha Orosaram Ratchaworawihan. However, Chinese elements remain. Wat Nang is an ancient temple that has existed since at least the late Ayutthaya period, specifically since the reign of King Thaisa. Inside the temple is an old bell with an inscription indicating the year 2260. However, this does not prove that the temple was built in that year. It could have been built earlier.

The reason for the temple's name, "Wat Nang," is not entirely clear, but two theories are still debated. The first suggests that many leather dolls were made at this temple in the past. Another theory posits that after the temple's construction, drums were systematically manufactured on the temple grounds, and numerous drumheads were stored there. Both theories are intriguing.

Prior to the reign of King Nangklao, Somdech Phra Sri Suralai, the royal mother (also known as "Than Riem"), had the entire temple rebuilt between 1824 and 1835. The reason for her decision to renovate and rebuild this temple is remarkable: the site was once the residence of Than Pheng, King Nangklao's grandmother. Therefore, it is understandable that a high-ranking member of the royal family, the king's mother, would choose to renovate this temple, even though it was located deep within a garden on the Thonburi side of the river.
