Jonggwangdae Toseong, located in Nosong-dong, Wansan-gu, Jeonju City, has been designated as a cultural heritage site (monument) of Jeollabuk-do Special Self-Governing Province. Jeonju City announced on the 20th that it had issued a notice designating Jonggwangdae Toseong as a cultural property after deliberation by the Jeollabuk-do Cultural Heritage Committee.

Jonggwangdae Toseong was built during the Later Baekje period for defense in the northern area of Jeonju. It is recorded in historical documents such as the 1530 compilation of "Sinjungdonggukyeojiseungram," as well as "Yeojidoseo," "Daedongjiji," and "Wansanji." Particularly, the ruins were first discovered during a housing redevelopment process in 2008, and subsequent excavations revealed that it was the fortress of Later Baekje.

The fortress was constructed using a unique method of using tiles and clay in a vulnerable defense area utilizing the topography of Bantae Mountain. This is evaluated as a rare case of applying the fortress construction technique of the Unified Silla period to a toseong. Additionally, during the excavation process, a large number of tiles in the Later Baekje style were unearthed, showing high cultural value.

The city plans to establish a comprehensive plan for the preservation and restoration of Jonggwangdae Toseong and to promote additional excavation and restoration projects following the designation as a cultural heritage site.

No Eun-young, Director of the Culture, Sports, and Tourism Department of Jeonju City, stated, "Jonggwangdae Toseong is a symbol of the Later Baekje royal capital and a precious heritage of Jeonju," adding, "Through continuous research and maintenance, we will strive to widely promote its historical value."
