era1900–1950 — Siam and the railway
2443–2493 — สยามกับรถไฟ
The train arrives, a gate is demolished for a straight road, and the moat gets its ring.
Unknown author · Public domainWhat it is
The railway reaches the east bank on 1 January 1921 and Tha Phae becomes the commercial street. Between 1910 and 1915 Chang Moi Gate and its earth bank are removed to run Ratchawithi Road straight to the river. The steel Nawarat Bridge opens 1923. The municipality is founded 1936 and in 1948 builds the roads on both banks of the moat, demolishing stretches of the wall registered as a monument thirteen years before.
The long version
Inference — 1948 is the year the square stopped being a fortification and became a roundabout. Everything the one-way loop does to the old city, for good and ill, dates from that decision.
