The Chapter House of Thuparamaya was built by King Bathikabhaya, also known as King Bathiyatissa. Today, only a few remains of the original structure can be seen.
These include several stone pillars at the lower part of the building, a simple moonstone, two guard stones, and a Korawakgala (a decorative stone balustrade). These ancient remains offer a glimpse into the architectural features and historical significance of the Chapter House within the Thuparamaya complex.
