Wat Phrammani

Most sources say the temple was built under King Rama V around 1896 and received consecrated boundary land in 1903, though one source dates it to King Rama I. No source explains the name "Phrammani". According to the temple's own account, Luang Pho Pak Daeng was brought from Vientiane by Lao migrants, is said to be a sibling of the Phra Suk and Phra Sai images, and was set down on the ground where the temple now stands. Another local tradition says that when King Rama V toured the Prachinburi area a royal elephant collapsed here, so he ordered a temple built as a memorial; a statue of Rama V stands in the vihara and two large elephant statues at the entrance (oral tradition, not documented).

Luang Pho Pak Daeng is a bronze Buddha in meditation, Lan Xang style, with a lap width of 49 inches and a height of about 1 m, robed in a pikul-flower pattern. Its slightly parted lips are painted bright red, which gives the name. It sits in the ordination hall, where people pray for luck, work and children, fulfilling vows with bananas, betel sets, garlands and red soda.

In late 1944 the Imperial Japanese Army 37th Division, raised at Kumamoto in 1939, was sent south to Nakhon Nayok to meet an expected British advance from Burma, and camped in the grounds of Wat Phrammani and nearby Khao Thurian. Japanese soldiers who died in the area were buried at the temple. After the war ended in August 1945 the division shipped home in May 1946 and was disbanded.

The division's veterans' association built the Japanese 37th Division Memorial at the temple, moving the buried remains into its platform in memory of about 7,920–7,929 dead. One source dates its dedication to 29 December 1989, while the Designated Areas for Sustainable Tourism Administration (DASTA) gives 1992.

The current abbot, Phra Thep Watcharaphromkhun (Sawat Wongklat), known as Luang Pho Tueng, began restoring the then-abandoned temple around 1983 and has been abbot since 9 April 1986 and has been Nakhon Nayok's provincial ecclesiastical head since 5 September 2011. He was raised to the Thep rank on 3 June 2026. Today the temple is busiest before the lottery draws on the 1st and 16th and at Songkran, when a replica of the image is bathed in front of the ordination hall. In 2026 the temple ran a Lent candle and bathing-cloth drive for remote temples, and on 20–23 October 2026 it hosted the province's Nak Tham first-level Dhamma exams.
