Wat Traphang Ngoen, "Temple of the Silver Pond", is the western counterpart to Wat Sa Si: a slender lotus-bud chedi on a square base, set on its own islet in a rectangular pond, reached by a wooden bridge. It is smaller and quieter than the more famous Wat Sa Si but the architectural form is essentially identical, and the temple is particularly atmospheric at sunset, when the chedi's silhouette catches the last light over the western rampart.
The standing Buddha in a mondop on the islet's east side, and the four ruined viharas at the cardinal points around the pond, give the temple a clear axial symmetry. Worth combining with Wat Mahathat and Wat Sa Si in a single morning ride within the central walled enclosure.
