chungjusanseong (충주산성)
There remains a lively debate over when exactly Chungjusanseong was built, and by whom. The valley within which the city of Chungju is nestled lay on the line of contact between all of Korea’s Three Kingdoms—Goguryeo, Baekje, and Silla—and so the area was fought over extensively from the 4th through the 7th Century. As such, no fewer than seven mountain castles on the UNESCO World Heritage list are located nearby. More to the point, while it’s likely that Baekje—the “original” owner of the land—built the castle, it might have been constructed by either of the other kingdoms during that tumultous period. Complicating the historians’ task further, throughout history the fortress has also been called by various names including Namsanseong, Geumbongsanseong, and Magoseong.
All that said, Chungjusanseong is an incredible example of what looks to me like Baekje-style castle construction, packed earth with a masonry shell. A couple rather unique innovations make Chungjusanseong stand out, however. First, and maybe most important, there are no stone ramps or even stairs at the gates. These gates are—and were—only accessible by external ladders which could be raised in time of need, providing an extra precaution against attack. Second, while wells and water sources are normally small or difficult to identify in castles of the era, Chungjusanseong’s water reservoir is not only prominent, it’s quite beautiful.
A final note on Chungjusanseong. While the scenery surrounding the castle—and the fortification itself—are truly breathtaking, this was by far the most difficult to find of all the castles we’ve visited in either Korea or Japan. There are no real markings at the trail head and so we missed it. After driving aimlessly on narrow gravel switchbacks, we had to stop and ask a local for directions. Given all the informative signage erected within the castle itself, apparently none was left to tell visitors how to get there. Well worth the trip . . . but consider yourself warned!
