Wat Parinayok Worawihan, Bangkok by Chaophraya Bodindecha

Wat Parinayok Worawihan is a third-class royal temple of the Worawihan type and is located at Parinayok Road 1, Ban Phan Thom subdistrict, Phra Nakhon district, Bangkok, under the Mahanikaya sect.

The original name of this temple was Wat Phrom Surin. It was built in 2353 (during the reign of King Phutthaloetla Naphalai) by Chaophraya Bodindecha (Sing Singhaseni), then known as Phra Phrom Surin. The temple was thus named after the royal title of that time. Under King Nangklao, the temple was renovated after his return from the war in Vietnam in Cambodia. However, as he died before its completion, King Nangklao simply handed the temple over to another king. It was recognized as a royal temple and further developed, receiving the new name Wat Parinayok in honor of Chao Phraya Bodindecha, then known as Samuha Nayok. The name Parinayok is derived from the word "Parinayok," which means "the great general and partner of the great emperor." The grounds of Wat Parinayok are located on the banks of the Khlong Bang Lamphu canal and are therefore narrow and elongated – often described as a "flag-shaped plot." The flagpole is located west of Khlong Bang Lamphu, with the end of the flag east of the Ministry of Agriculture and Co-operatives' grounds. Originally, the temple grounds covered a wide area, stretching from Lan Luang Road opposite Mahakan Fort at the foot of Phan Fa Lilat Bridge to the temple's current location.

When Ratchadamnoen Road was built in 1899 (during the reign of King Chulalongkorn), its route cut through the grounds of Wat Parinayok, causing the temple to lose a significant portion of its area. King Chulalongkorn therefore ordered the reconstruction of Wat Parinayok. This involved building a new chapel and incorporating the serpentine leaves from the old chapel into the design of the new one.
