The temple, of archaeological, historical, and social importance, was declared a national ancient monument in Aug 2001. The ordination hall (sim or ubosot) of this temple houses magnificent murals, both inside and out, painted by a folk artisan from Maha Sarakham known as Thong Thipcha. The building originally had a northeastern roof style with an extended roof on each side. Later, a new roof of the Rattanakosin-style replaced the old dilapidated one. In 1993, the roof was extended to shelter the murals from the elements. There is also a folk museum nearby where rare folk implements of the region are on display.
พิพิธภัณฑ์แห่งชาติขอนแก่น
The Khon Kaen National Museum was opened by King Bhumiphol Adulyadej on 20 December 1972. It exhibits antiques and precious art pieces from pre-historical periods as well as a skeleton of the New Stone Age man and tools found at Ban Chiang. Interesting exhibits include stone lintels from Khmer ruins in the region as well as art from other periods, namely the Sukhothai and Ayutthaya, and native tools. These exhibits deepen knowledge of the history, archaeology, and the lifestyles of Isaan. Most of the archaeological excavation was conducted at the Muang Fa Daet Song Yang site in Ban Chiang.
พระมหาธาตุแก่นนคร หรือพระธาตุ ๙ ชั้น
A royal temple, the Phra Mahathat houses relics of the Lord Buddha and important Buddhist scriptures. It was established to celebrate the Golden Jubilee Celebrations of King Bhumibol Adulyadej's accession to the throne and to celebrate the 200th anniversary of Khon Kaen Province's establishment. Doors and windows of the 9 storeys of the stupa are beautifully carved, featuring the life and former incarnations of the Lord Buddha, 16 classes of visible deities in the Brahma's world, and Buddhist rites. Murals within the stupa feature the history of the town. Its spire, Isaan fishnet shape, and Indochina-Dvaravati-era style, imitated Phra That Kham Kaen. Its base is a square shape of 50 meters on each side and 80 meters in height, where are four mini-Buddha's relics at each corner sheltered by a seven-head-nāga crystal wall. The top floor, on the ninth storey, houses relics of the Lord Buddha. Visitors can enjoy a panoramic view of the town from there.
สิมอีสาน
Sim Isaan, a term for northeastern ordination halls or Ubosot, is within Wat Pa Saeng Arun, Phra Lap. The Sim Isaan’s outstanding features lie in its typical shape and style and solidity, as well as the beauty of the murals of Mudmi patterns of the province’s famous tie-dyed silk. This has been intended for later generations to learn from and treasure as well as to conserve local architecture.
