Ungjin
Ungjin, also known as Gomnaru ( Hangul: 곰나루, literally " bear port") is a former city on the Korean Peninsula. It was located in modern-day Gongju, South Chungcheong province, South Korea. It was the capital of Baekje from AD 475 to 538, during a period when Baekje was under threat from Goguryeo, the previous capital of Wiryeseong (modern-day Seoul) having been overrun. In 538, King Seong moved the capital to Sabi (in modern-day Buyeo County). Ungjin is now known as Gongju.
Notable historical places of Ungjin Baekje are Gongsan Fortress and Tomb of King Muryeong.
