Named for the God of Dawn, Decorated with Broken Chinese Porcelain Used as Ship Ballast -- Wat Arun takes its name from Aruna, the Hindu god of dawn, yet despite the name it is not necessarily best viewed at sunrise -- many visitors find the temple's silhouette most striking from across the river at sunset, when its central prang catches the fading light. The spires are covered entirely in fragments of Chinese porcelain and seashells, a decorative technique born of practicality: Chinese ships arriving in Bangkok once used porcelain as ballast, and once unloaded, the broken or surplus pieces were donated to the temple rather than discarded. What looks like an elaborate ceramic mosaic designed from the start was actually assembled piecemeal from material that would otherwise have gone to waste.
