Huge water storage facility discovered at Baekje's Iksan Earthen Fortress in Korea...Fragments of lacquered leather armor also found

A water collection facility for storing water was newly discovered at the ruins of an ancient Baekje city in Iksan, Jeollabuk-do, Seobu, South Korea. Excavations at the site revealed that the building was constructed as an earthen fortress in the late Baekje period.
The existence of a water collection facility located to the south of the "Iksan Earth Fortress" was revealed. Fragments of lacquered leather armor and pieces of wood (presumably for document classification) were also unearthed from this facility.
The Korea National Heritage Administration announced on the 30th that a water collection facility measuring 9.5 meters wide, 7.8 meters long, and 4.5 meters deep at its maximum was confirmed within the grounds of Iksan Earthen Fortress.
The facility is a huge circular stone water collection facility made from processed natural bedrock, with the floor and lower part remaining completely intact. Fragments of lacquered leather armor were also excavated from the water collection facility. These fragments were discovered in
The site is the third to be discovered after Gongsanseong in Gongju, South Chungcheong Province, and the Gwanbuk-ri site in Buyeo. Fragments of roof tiles and earthenware from the ancient Baekje period were also discovered at the same time.
In particular, fragments of sticks used for sorting documents were also found, which suggests the period when Iksan Earth Fortress was in operation.
The stick, 2.3 cm in diameter, has "Jeongmi Geum Jae Shik (food that remains today)" written on it in ink, and if it is identified as a fragment of a stick, a type of mokkan (wooden strip with writing on it), it is believed to be the origin of Baekje.
It could be an important research resource for civil engineering technology in the world. Iksan Earthen Fortress, also known as "Ogeumsan Fortress," is the remains of a mountain fortress surrounded by Ogeumsan Mountain, 125 meters above sea level, and excavation work has been ongoing since 2017.
A large number of "capital inscription tiles," which refer to tiles from the palace where Baekje kings lived, have been unearthed, and these discoveries suggest that Iksan Toseong is related to the Wanggung-ri archaeological site, located about 2 kilometers south.
The Korea National Heritage Administration said, "Based on the results of this excavation, we plan to formulate a systematic development plan for the Iksan Earthen Fortress."
