กรุงเทพฯ ไม่ใช่เมืองเก่าเพียงย่านเดียว
George Town has a canon. Vigan has an intact grid. Hoi An has a complete timber town. Bangkok has something harder to conserve—and potentially more important: many living old towns operating inside one metropolis. This is the case. The missing evidence stays visible.
The proposition
A UNESCO inscription is not a beauty contest. It tests Outstanding Universal Value, integrity, authenticity, protection and management. Bangkok cannot honestly claim those conditions citywide yet. It can test a stronger proposition: nowhere else in the comparison combines this breadth of rowhouse types, infrastructures, communities and active metropolitan use. The current machine screen adds 2,311 present-day building shapes to inspect, but none enters the evidence column until archival or field review confirms it.
Claim register
The mapped evidence already spans palace frontages, Chinese wholesale blocks, tenant-led conservation, Thonburi markets and a canal-facing timber settlement. Bangkok is not one picturesque core.
29 sourced corridors · five rowhouse types · 26/46 official records locatedFine Arts records, academic inventories and conservation cases repeatedly identify shophouse rows—not only temples and palaces—as the structure connecting trade, dwelling and public space.
870+ individually counted units · CPB inventory: 1,960 units across 15 sites (not added because records overlap)Bangkok's documented typologies and infrastructures are unusually varied. Proving comparative exceptionality requires a citywide inventory and a consistently defined boundary, which do not yet exist.
Comparative thesis; not yet a completed inventoryWorld Heritage requires boundaries, integrity, authenticity, protection and management—not simply many old buildings. Fragmented controls and redevelopment pressure are currently weaknesses in Bangkok's case.

Official UNESCO statements for comparator sites; a critical research proposition for Bangkok.
No proposed boundary yet; this atlas maps 29 dispersed corridors and reconciles 26 of 46 ONEP category-E records
870+ units counted in mapped ensembles; a separate CPB inventory reports 1,960 units across 15 commercial sites, with overlap not yet reconciled
