Largest Three Kingdoms-era fortress gate discovered in Buyeo

Archaeologists have unearthed the largest ancient gate structure from the Three Kingdoms period in Buyeo, South Korea, a discovery that promises to reshape our understanding of Baekje's defensive capabilities and urban design. The East Gate of the Buyeo Naseong fortress, identified during an excavation project, measures approximately 10 meters in width.

This finding is particularly significant as most previously discovered gates from the Three Kingdoms era typically range from 4 to 5 meters wide. Even the West Gate of the Pungnaptoseong Fortress in Seoul, considered a large example, measured only about 7 meters. The sheer scale of the Buyeo East Gate suggests a more robust and imposing entrance to the ancient capital.

The excavation also revealed evidence of a gatehouse structure, known as a 'munru,' and two distinct passage routes. These features offer valuable data for reconstructing the entry and defense systems of Baekje's Sabi capital, as well as its overall urban planning. The presence of wooden pillar foundations in the center of the gate suggests a sophisticated design for managing traffic flow for both people and carts.

Researchers noted that the gate's construction techniques, including the use of stone foundations and walls, align with known Baekje stonework methods. Evidence of at least two modifications to the gate itself was also observed. Buyeo County plans further detailed excavations starting next year, aiming to fully uncover the gate and its surrounding structures, further illuminating the historical significance of the Baekje capital.
