Bangkok's temples are concentrated for an administrative reason rather than a devotional one. When Rama I moved the capital across the river in 1782 he rebuilt the Ayutthaya religious establishment on the new site, and every reign since has added to it, so the old royal city holds a density of royal monasteries found nowhere else in the country. The grading you will see quoted — first, second and third class, with sub-ranks such as Ratchaworamahawihan — is an official fact recorded in the state registers, not a ranking invented for visitors. It is also the single most useful thing on a temple page, because it tells you why one temple outranks another.
These eighteen pages cover the temples most people come for, and then the ones they find next. They are built from the Fine Arts Department's national monument register and its published monographs, the Department of Religious Affairs temple register, the Bureau of the Royal Household, UNESCO, named university and research-institute databases, and the temples' own publications. Where a claim you have read elsewhere turns out to rest on nothing we could check, this guide says so rather than repeating it — and there are more of those than you might expect, including the step count at the Golden Mount, the quarry that supplied the Marble Temple and the reason the Giant Swing stopped swinging.
11 of 18 temples in Bangkok are plotted. The others have no confirmed coordinate yet, so they are not shown as pins.
Every page is built from the National Office of Buddhism and Department of Religious Affairs registers, the Fine Arts Department’s national monument register and its published monographs, the Royal Gazette where it could be read, UNESCO, and the temples’ own material — with the Tourism Authority of Thailand used only for visiting practicalities, never for history. Nothing here is taken from a travel blog, a listicle or a review site.
The rule that governs every page is that recorded tradition is not history. Thai temple histories are full of foundation legends, and they are worth telling — but told as tradition, in those words, never flattened into a bare founding date. Where a date is not established, the page says so, and that sentence is the useful part.
Still to come here: Bangkok is complete at eighteen temples over three runs. The queue advances to Chiang Mai: Wat Phra That Doi Suthep, Wat Chedi Luang, Wat Phra Singh, Wat Chiang Man, Wat Umong and Wat Suan Dok. Wat Pho Chai, once listed here, is in Nong Khai and belongs to a Nong Khai run.
Read the guide to Buddhism and temple etiquette in Thailand first — dress, footwear, photography and how to behave around monks. Then the Bangkok city guide and things to do in Bangkok for everything around them.
