Phitsanulok
city in Phitsanulok province, Thailand
Phitsanulok (Thai: พิษณุโลก, pronounced [pʰít.sà.nú.lôːk]) is a city municipality in northern Thailand and the capital of Phitsanulok province. In 2024 it had a city population of 60,827 and an urban population of about 200,000. That made it Thailand's 19th-most populous city proper and one of the major urban centers of the north. Located in the geographic center of the province, it occupies the fertile plains along the banks of the Nan River, which flows south to join the Chao Phraya River.
The city grew from an older settlement called Song Khwae (lit. 'two rivers'). It was a second capital more than once: under the late Sukhothai Kingdom, and under the Ayutthaya Kingdom, when King Borommatrailokanat resided there to hold the frontier against the Lanna Kingdom. He unified the western and eastern Song Khwae settlements and renamed them "Phitsanulok". Due to its strategic importance as Ayutthaya's northern outpost, the city frequently faced Burmese attacks. When war with the Konbaung dynasty led to Ayutthaya's collapse in 1767, Chaophraya Phitsanulok declared himself king and briefly established Phitsanulok as a capital before it was incorporated into the Thonburi Kingdom. The city maintained its significance throughout the subsequent Rattanakosin period.
This brief starts where responsible research should: with the source description of “Phitsanulok” as city in Phitsanulok province, 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 city in Phitsanulok province, Thailand. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q867579. Authority coordinates are 16.816, 100.264. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2024 and 1767.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.
