Suvarnapura, 'golden town', is the name on the Preah Khan list and the later Thai Suphannaphum.
It stands on the Tha Chin, the second mouth of the delta, with salt pans behind the coast and the old Mon town of U Thong to the west. Suphan Buri and Lopburi are the two poles of the lower basin in the later Thai chronicles: in 1351 they are joined in Ayutthaya. The 1200 evidence is the name on the list and the plain's Khmer-language inscriptions; there is no named lord and no Khmer building we could confirm.
Khun Luang Pha Ngua, the Suphan Buri ruler of the Ayutthaya story, belongs to the 14th century.

Where the sources disagree
- The campaign board entry suphannaphum-suphan-buri 'likely': agreed that its standing in 1200 is not known.
- English Wikipedia (Lavo Kingdom) after Wyatt: sixteen dated inscriptions of 1168-1219 from Lopburi and the western plain show no sign of Angkorian political or administrative power ('not conclusive'); Baker and Pasuk: the plain has none of the temple-endowment inscriptions typical of Angkorian provinces. The Preah Khan stele of 1191 lists six western towns among the 23 that received Jayabuddhamahanatha images.
Evidence: One name on one stele's list.
"The campaign board" is OMNIA's working map. These notes record where its earlier claims were checked against the sources.
On the map: A block round the seat; the plain has no frontier.
