“The Mae Nak Phra Khanong legend originated in the Phra Khanong canal area of Bangkok in the mid-19th century (around the 1850s–1860s), during the reign of King Mongkut (Rama IV).”

The claim gets the place right but likely gets the historical timing wrong. Evidence consistently ties Mae Nak to the Phra Khanong canal area, yet the better-supported historical accounts place the underlying incident in the late reign of Rama III, not in the 1850s–1860s under Rama IV. Because the date and reign are central to the claim, this is more than a minor caveat.

“The Mae Nak Phra Khanong legend is associated with Wat Mahabut in Bangkok, Thailand.”

The evidence clearly supports the temple association. Multiple reliable sources identify Wat Mahabut in Bangkok as the shrine site and principal religious location tied to the Mae Nak Phra Khanong legend. Administrative district wording can vary, but it does not alter the core fact that the legend is associated with Wat Mahabut.

“A shrine dedicated to Mae Nak exists at Wat Mahabut in Bangkok, Thailand, and visitors leave offerings there including traditional Thai dresses, cosmetics, and toys for her baby.”

Evidence consistently shows that Wat Mahabut in Bangkok has a shrine dedicated to Mae Nak. Multiple independent descriptions also report visitors leaving votive offerings there, including Thai dresses, cosmetics, and toys associated with her baby. Some sources focus only on basic prayer items, but that does not conflict with the broader record of additional offerings.
