Wat Phanom Yong officially translates to "The Temple of the Wet Nurse Yong". The still-active monastery initially built on a garden owned by a King's wet nurse was eventually built by the latter in her honour. Although abandoned after the fall of the Ayutthayan empire, it was maintained by the Yong family.
Built during the reign of King Narai, Wat Phnom Yong was rebuilt by King Chulalongkorn between late 18th and early 19 centuries. With a double-tiered roof, the ubosot is supported by four columns. The elevated front porch has three entries. Hosting a vihara containing a sizeable reclining Buddha statue, the main prayer hall walls are designed in attractive murals. Wat Phanom Yong also has a crematorium building in the vicinity.
