Yaowarat & Samphengเยาวราช–สำเพ็ง
Chinatown proper — 1782 lane, 1890s boulevard, five and a half tonnes of gold.
When Rama I took the land under today's Grand Palace for his capital in 1782, the Chinese traders already living there were moved downriver to Sampheng. The lane they built — now Soi Wanit 1 — still runs its original course, a covered kilometre of fabric, buttons and gold shops barely two metres wide. Yaowarat Road, the dragon-curved boulevard the neon knows, came a century later, cut between 1891 and 1900 as Chinese Bangkok's front street.
Wat Traimit, at the quarter's eastern gate, holds the Golden Buddha: five and a half tonnes of solid Sukhothai-era gold that spent two centuries disguised under stucco — the plaster cracked during a move in 1955 and the gold looked out. Wat Mangkon Kamalawat (1871), the largest Chinese temple in the city, anchors the Teochew religious calendar; during the vegetarian festival the whole of Yaowarat goes yellow-flagged and meatless. The Odeon Gate, raised in 1999 for the King's sixth-cycle birthday, closes the boulevard's eastern end like a punctuation mark.
The register's entries here are mostly not temples but shophouse runs — Sampheng lane itself, Ratchawong, Song Wat, Yaowarat — protecting the fabric of the trade rather than any single building, which is the honest way to protect a market quarter.
