Studies on Baekje mountain fortress wall during Hanseong period (the period when Baekje established its capital around Han rivers) are still in an early stage of study. 34 Baekje fortresses of Hanseong period (BC18 AD475) are listed in 〈SamgukSagi〉, out of which 8 fortresses have been estimated to be wooden fortress and most of them, mud fortifications, As excavation of fortresses have been carried out actively around Kyeonggi areas recently, however, it has been suggested that Banwol fortress at Pocheon. Seolbong fortress at Icheon and Seolseong fortress at Icheon were constructed during Hanseong period, attracting attentions from related area. This means that the mountain stone fortress of well-heaped girth already emerged during Hanseong period.
There are several ground for suggestion that these fortress were built in Baekje period. First, Baekje relics have been excavated inside fortress and compacted layer below foundation, Secondly, the compacted day or supplementary stone wall technique found inside the inner wall are different from those of the fortress from Shila Period. However, since the cultural layer of Baekje period formed after construction or fortress was not clear, and gangway type gate structure, well-ordered fortress construction method, section structure of wall, size and shape of castle stones are estimated to be very similar to those of fortress from Shila Period constructed after 6th century, conventional opinion should be reconsidered.
According to study results up to now, most fortresses of about 800 fortresses examined in Baekje area are known to be border type and about 50% are mud fortress. The representative fortresses of Baeje fortress during Hanseong period include Gomori fortress at Pocheon. Wolrong fortress Paju and Morak fortress at Uiwang. These fortresses constructed castle walls focusing on mountain top, where mud fortresses were the main part and its protection ability was reinforced with crude stone fortress of stone wall or combination or mud and stone type in part. In addition, since Baekje fortresses during Hanseong period were estimated to be mainly distributed in the areas above the Imjin river and below Yeseong river, it is realistically difficult to grasp the fact with overall aspect only.
