The chedi (fig.) of Bangkok's Wat Prayun Wongsahwaht is surrounded by a circular wall, that was added later and which is topped by 18 smaller pagodas.

On the inside of the circular wall are open doorways, that give access to a gallery, which on one side is used as a columbarium wall, with three continuous rows of niches to accommodate cremated remains, each niche closed off with a small memorial plaque.
