Wang Pho ViaductAlso called Wampo Viaduct or Tham Krasae Railway Bridge, the structure was constructed by allied prisoners of war under Japanese command during World War II and forms part of the infamous Burma Railway.
The viaduct runs on wooden trestles set against the cliff face, following a narrow ledge above the Khwae Noi River; a nearby smaller viaduct gives the site the informal name Double Viaduct.
The line remains in use for local trains, and the site combines industrial heritage, stark wartime history and striking riverside scenery.
