Wat Pahk Nahm Phasi Chareun (fig.) is a royal temple in Bangkok's Phasi Chareun district. Both its name signs and small ho trai, i.e. the library, have been richly decorated with waen fah, i.e. inlaid with pieces of mirrored-glass (fig.).

The library or ho trai, were manuscripts are stored in lacquered scripture cabinets, is typically built on poles in a pond or water basin (fig.), in order to protect them against fires, as well as to prevent crawling insects and termites from reaching the scriptures and damaging them (fig.).

In a part of the covered hallway, where a shrine is dedicated to Phra Mongkhon Thepmuni (fig.), the influential abbot from 1916 until his death in 1959, the eave brackets, which have been designed in the form of a Garuda (fig.), are also inlaid in the waen fah-style.
