A Shaivite sanctuary on an extinct volcano, reached by a stone causeway and a stair, with the temple of Muang Tam and its ponds on the flat below.
It watches the road north from the Dangrek passes to the Mun. The place was built and rebuilt across three centuries, and Jayavarman VII's additions (a hospital chapel, the rest house, the pavilion where the king changed his dress) show it in use in the years round 1200. Thai accounts call the family that held it a regional princely line. We give no name for the lord of this winter.
The sanctuary turned Buddhist at some later date.
Who he is
- Title
- Lord of Phanom Rung (a regional prince of the Angkor court)
- Since
- not known
- Born
- not known
- Family
- The campaign board says a local princely line related to the Angkor court. The names usually given are Narendraditya, a prince of the Mahidharapura house, and his son Hiranya, for the 12th century (from memory of the Phanom Rung inscriptions, not re-read this session; English Wikipedia's Phanom Rung page names neither). Nobody is named for 1200.
- Confidence
- low
English Wikipedia (Phanom Rung Historical Park; Prasat Muang Tam): two brick sanctuaries of the 10th century, a sandstone Prang Noi of the 11th, the central sanctuary in the 12th (the page says under Suryavarman II), two library halls of the 13th; under Jayavarman VII the pavilion for changing royal dress, the Kudi Rishis of Nong Bua Ray, a hospital chapel (arogyasala) and the rest house at Prasat Ban Bu. The page calls it an important vice-regal centre. Muang Tam: late 10th and early 11th century, four L-shaped ponds, a later and larger baray between the two temples.
Overlord
Angkor; kin of the royal house on the campaign board's reading.
What it holds
- The mountain sanctuary and its causeway
- Muang Tam and its ponds and reservoir
- The village lands and the baray between them
- The road north from the Dangrek passes, with the rest house at Prasat Ban Bu and the hospital chapel
How it was acquired
Not known; the family is argued from 12th century inscriptions.
Allies and rivals
The Angkor court; Phimai to the north-west; the Kui of the Dangrek.
How things stand that morning
In use and in favour: the king's own additions are recent. Lord not known.
Wealth
Temple endowment villages, the water of Muang Tam, the toll of the pass road.
Military
None attested.
Threats
- The slow silting of the reservoirs
Places of note
- Phanom Rung: Shaivite sanctuary on the volcano.
- Prasat Muang Tam: Temple with four L-shaped ponds.
- Prasat Ban Bu: Rest house of the royal road (placed in the district).
Where the sources disagree
- The campaign board entry phanom-rung: 'a local princely line related to the Angkor court'. The line is argued from inscriptions we did not re-read; English Wikipedia gives only the building phases.
- The campaign board entry muang-tam (14.497, 102.976) agrees with the Wikipedia coordinates (14.4967, 102.9836) to under 1 km.
Evidence: Buildings and phases are firm; the princely line is from memory and the campaign board.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
