East gate

The main gates are used for entering and exiting the fortress. Their number depends on the topography upon which the fortress is built, but most compounds have one in each of the four cardinal directions. At Namhan Mountain Fortress, the East Gate (or Left-wing Gate 左翼門) and the South Gate are the most frequently used entranceways. The North Gate (or Total Victory Gate 全勝門) was built in 1624, and the West Gate (or Right-wing Gate 右翼門) was where King Injo and his Crown Prince left the fortress to surrender to the Qing army on the 30th day of the 1st moon in 1637.
