Kyonggi Bay

Kyŏnggi Bay lies at the mouth of the Han River on Korea's western coast, where islands and tidal channels approach the capital's river. Kanghwa Island guards the northern entrance. During the Mongol invasions, the Koryŏ court moved from Kaegyŏng to Kanghwa in 1232. Under Joseon, forts and watch posts defended the island's shores, reflecting its importance near the routes to the capital.
