Wat Sangkas Rattana Khiri most well-known for its Devo Merit-making festival, which is usually organized on the first day of the waning moon during the 11th Lunar Month. Hundreds of monks residing within the district walk down the 449 steps from the top of Khao Sakaekrang Mountain to accept food offerings from Buddhist devotees.
The ceremony was initiated to replicate the Buddhist Legend, in which Lord Buddha makes his way back to earth after completing his visit to his Mother in heaven during the Buddhist Lent. As such, the end of the Lent marks the so called 'Devo Lo Ha Na', the day of the open gate to welcome Lord Buddha back to earth. This day is believed to be the day that Lord Buddha opened access to the 3 worlds (earth, heaven, and the underworld).
Wat Sangkas Rattana Khiri was chosen to perform this ceremony because its setting and geography comes nearest to the atmosphere of the Buddhist Legend. The temple, situated at the beginning of a mountain range, is also among the oldest and best known temples in the province.
At the foot of the mountain, the main hall houses the captivating bronze Buddha image of 'Phra Buddha Mongkol Saksit' or 'Luang Pho Mongkhon' in Sukhothai period style that has been much worshipped over generations. From here to the top of the mountain, there are several pavilions complementing this complex. One pavilion houses a big replica of Lord Buddha's footprint to suggest his visit to this place.
Near the top of the stairs, there is a large bronze bell built in the reign of King Rama V, which is said to be a sacred bell, and ringing this bell is a must for every visitor to the province. Yet another pavilion houses the statue of the father of King Rama I, the founder of the current Chakri dynasty, who was born in Ban Sakae Krang, Uthai Thani.
All in all, this is a very diverse temple complex with a strong connection to the Buddhist Legend.
