The works are the visible organisation of the state.
The Preah Khan stele of 1191 counts 121 rest houses ('houses with fire', vahnigrha, dharmasala) along the royal roads, 17 of them on the road to Phimai and 57 on the roads to Champa (English Wikipedia, Phimai), and 102 hospital chapels (arogyasala) for the people, each with its foundation stele; seven such steles dated Saka 1108 (1186) are known, five from the Nakhon Ratchasima region (same article), another at Sai Fong near Vientiane. Stone comes from the Kulen quarries by canal, laterite from the plain; the roads are raised and carry bridges with corbelled arches (Spean Praptos, Spean Ta Ong). The labour is the endowed servants of the great foundations.
The totals are the king's claims, not counts: fewer than half the hospitals are identified on the ground (English Wikipedia, Arogyasala).

The stelae of Ta Prohm (1186) and Preah Khan (1191) as reported in English and French Wikipedia and in Higham; seven hospital stelae of Saka 1108 (1186) (English Wikipedia, Phimai).
What it holds
- Roads east to Champa and Preah Khan of Kompong Svay, north to Phimai (225 km, English Wikipedia), north-west to Banteay Chhmar, west to Lavo (nothing listed in the stele)
- Rest houses (17 on the road to Phimai; 57 on the roads to Champa; 121 in all)
- Hospital chapels (102 claimed; at Ta Prohm Kel, Ta Muen, Koh Ker's Prasat Andong Kuk, Prang Ku in Chaiyaphum, Ku Santarat, Sai Fong and others)
- The Kulen sandstone quarries and loading canals
- The corbelled bridges
How things stand that morning
In use. Work on the Bayon and Angkor Thom is the largest call on labour; nothing is dated to 1200.
Wealth
Tens of thousands of endowed servants by the stelae's claims.
Threats
- Silting of canals and barays; the labour cost
Places of note
- Spean Praptos: The longest corbelled bridge.
- Kulen quarries: Sandstone for the temples.
Where the sources disagree
- Board 'khmer-west-road-rest-houses': the western line is inferred; the Lavo page on English Wikipedia says hospitals and fire houses reach no further west than Prachin Buri.
Evidence: Stele claims, partly confirmed on the ground; the officers are unnamed.
On the map: A block for the first stages of the eastern road and the quarries; the full network is in the religious records.
