History & naming
Most areas of Wachiraphayaban are in Samsen quarter, Samsen is an area with a long history before the establishment of Rattanakosin in 1782, since the Ayutthaya period in the reign of King Narai this was where the Immaculate Conception Church was located, and the Portuguese community.
Until the early Rattanakosin period, the Christian Khmers escape their country to settle here with the royal permission of the King Rama I. Later in the reign of King Rama III, there were also a group of Christian Annamese settlers here as well, and they built another church, St. Francis Xavier Church. Thus making Samsen a settlement of both people races, hence the named "Ban Khmer" (บ้านเขมร) and "Ban Yuan" (บ้านญวน—Yuan is old Thai language colloquialism used for Annamese).
Before 1939, then named Ban Yuan Samsen. (บ้านญวนสามเสน)
The eponymous Vajira Hospital, the old government hospital since the reign of King Rama VI on Samsen Road.

This brief starts where responsible research should: with the source description of “Wachiraphayaban subdistrict” as subdistrict in Dusit district, Bangkok, Thailand. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as subdistrict in Dusit district, Bangkok, Thailand. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 4, 2025. The linked authority identifier is Q15735955. Authority coordinates are 13.781, 100.504. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1782 and 1939.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
