Hwaseong Dangseong (당성)
Dangseong is an historically rich location that is gaining greater attention as Koreans look to their own long history. Originally constructed in the 3rd-4th Centuries A.D. by Baekje, it has the distinction of being one of only a handful of fortresses owned and manned by all three Korean kingdoms. Intended to protect the nearby port, Dangseong became the primary gateway to trade with the various Chinese dynasties that rose and fell from power throughout that millennium. As such, Dangseong served to protect that vital trade route all the way through the Joseon Era, an incredible usage spanning over a thousand years. Dangseong is also noteworthy in that, unlike other Baekje fortresses built of rammed earth and later fronted with stone, this fortification seemed to evolve in the opposite direction. The initial, small fortress was clad in stone and later additions by Unified Silla and Goryeo—with far fewer enemies so far south—included stretches of rammed earth walls. It makes some sense as the expansion was intended more to handle the vast influx of trade goods going to and from China than it was to truly expand the fortress’s inherent defensibility.
