Bunhwangsa Stone Brick Pagoda, constructed in 634, is Korea's oldest stone pagoda. As a prototype of the Silla Stone Pagoda, the pagoda was constructed using flagstones. Since it was constructed with flagstones, it has been known to be a pagoda that replicates the brick pagoda until now. The latest research suggests that it copies the India Stupa or the Stacked Stone Pagoda more than the Brick Pagoda. However, the Bunhwangsa stone brick pagoda has a significant difference in terms of construction technique and shape compared to Brick Pagodas, India Stupas, and Stacked Stone Pagodas. Therefore, it is worth paying attention to the stone building technique used in Silla. Through this study, I would like to clarify that the Bunhwangsa stone brick pagoda is a stone pagoda that creatively reflects the existing Silla stone building techniques such as stone fortresses and stone chamber tombs.
