Peaceful place and quite informative with information in Thai and English. The 300+ years old tree (where King Taksin sit and planned his battle) was impressive and well taken care of.

I used to ordain and became a Buddist monk at this Wat Lum-Maha-Chai-Chumpol temple about 30 years ago. It used to be a very small temple in downtown Rayong then. Wat Lum Mahachai Chumpon Temple was constructed about 290 years ago during Ayuthdhaya period. After Ayudhaya was invaded by Burmese army in 1767 AD , King Tak Sin brought military and civilians to the East and made a stop for temporary camping before moving to Chantaburi at the temple location, it was told that King Tak Sin tied his troop's elephants and horses at the large Sa Tue tree which is still alive in front of King Tak Sin shrine nowadays. The original Wat Lum Temple area was a lowland ( Lum means low land), flooding occurred every year during rainy season. The King Tak Sin shrine is one of the attraction that local Thai often visit.
