The Historical and Cultural Value and Significance of Pasaseong Fortress in Yeoju

This article reviews the archaeological survey results and research history of the Pasaseong Fortress in Yeoju, and explores its historical, archaeological, and cultural value and significance. To date, ten excavation surveys have been conducted at Pasaseong Fortress, yielding significant academic achievements. Architectural features such as the hyeopchuk-style construction method—where the fortress walls are built with stone masonry on both the inner and outer sides, the hyeonmun-style gate with its entryway located in the upper part of the wall, curved walls, and pedestal-reinforced construction have been dated to the mid-6th century. However, based on the remains and artifacts unearthed within the fortress, its core period of use is more accurately dated to after the mid-8th century, which aligns more closely with the archaeological evidence. Pasaseong Fortress is a historical military defense site that integrates literature, history, and philosophy. It has served as a source of inspiration for many literary works, including poetry and prose by prominent scholars. The site also preserves historical events and reflects the chronological evolution of Korean fortress architecture. During the Joseon Dynasty, it embodied the philosophical ideals of Yoo Seong-ryong’s defense policies as they were put into practice. As such, the process of overcoming the Imjin War—the greatest national crisis in Joseon history—can be better understood in the broader context of the defense strategy implemented around Hanseong Fortress. In this way, Pasaseong served as the only strategic stronghold connecting the Namhangang River to the main stream of the Hangang River. Functioning continuously from the Three Kingdoms period through Unified Silla, Goryeo, and Joseon Dynasty, it has played a quiet yet significant role in the flow of Korean history. Pasaseong Fortress fulfilled a multifaceted role—spanning politics, economy, society, culture, and defense—from ancient times through the modern era. It is considered a rare example of a military fortress that encapsulates not only historical events but also literary and philosophical heritage. In modern times, among the large-scale civil engineering projects along the Hangang River—such as Gangcheonbo Weir, Yeoju Weir, and Ipo Weir—the Ipo Weir forms a unique belt that connects Pasaseong Fortress to Taebong-sanseong Fortress. This connection encompasses Iponaru, Cheonseori, and Dangnam-ri Islands, creating a distinctive and naturally integrated infrastructure. Pasaseong Fortress thus embodies the gravity of history, which judges the successes and failures of past eras from both contemporary and retrospective perspectives.
