The Sarira Pagoda, or Stupa, is slightly smaller compared to pagodas. Nevertheless, its beautiful, delicate carvings on all sides of the pagoda are incredibly impressive. The Stupa of Bulguksa Temple holds the designation as a National Treasure.

"Sarira" is a Buddhist term referring to the remains of Sakyamuni Buddha or a monk following cremation. The shape of a Sarira can vary from a round ball to a small particle. Sariras are generally believed to be the result of prolonged periods of meditation and prayer. A Sarira pagoda is a place where the sariras, particularly those of renowned Buddhist monks, are stored.

The Stupa of Bulguksa Temple was stolen and illegally transported to Ueno Park by a Japanese in 1905. It was returned later in 1933. This incident signifies the unfortunate history where Korean cultural heritage suffered during the period of Japanese Colonial rule.
