Following the defeat of Baekje in the 660s, the Baekje architect, Abiji, was commissioned to build a nine-story wooden pagoda at the site, and labored with two hundred artisans to complete the pagoda. This fact indicates that the Baekje had superior knowledge of wooden architecture. The nine stories supposedly represented the nine nations of East Asia and Silla's future conquest of those states. The pagoda stood until it was burned by Mongolian invasions in 1238. No wooden architecture from the Silla people survives today but the ruins of Hwangnyongsa suggest a Goguryeo influence.
