Once graced by the presence of King Rama V during his exploration of the region in 1908, this royal hall witnessed a profound moment when His Majesty chose to offer his insights, signifying its importance in history. According to King Rama V’s journal about the trip along the Makhamthao River, His Majesty’s understood that Krommakhun Phornphinit (Prince Uthumphorn or Khunluang Hawat) entered his monkhood at Wat Pho Thong and built this residence as a lodging during the Buddhist Lent since it was a strategic site. Having seen that the residence was beautifully constructed, King Rama V realised that Krommakhun Phornphinit couldn’t have built this residence as temporary lodging or a strategic outpost. Thus, it is believed that the residence’s construction dates back to the reign of King Borommakot, upon his frequent visits to this area, in parallel to King Prasatthong who constructed his residence in Bang Pa-In. Due to a preference for this locale and paying homage to the reclining Buddha image in Wat Khun Inthapramun twice, Krommakhun Phornphinit led his loyal subjects and monks from Ayutthaya and stayed at Wat Pho Thong Khamyat and Kham Yat Palace Hall to join Bang Rachan villagers.
