The chedi of Bangkok's Wat Prayun Wongsahwaht is a hollow structure and can be visited on the inside. The interior consists of bricks and initially had only a central pillar made of brick and a few wooden support beams. In 1871 AD, the pagoda was struck by lightning and damaged.

It remained unrepaired for nearly 47 years, until 1918, when it was restored and reinforced with steel. Today the niches below display Buddha images in different poses, including those of the Phra prajam wan system (fig.).
