The wall was originally built using soil in 1396, then reinforced with stone blocks during the reign of King Sejong in the 15th century.
Stone blocks used in the wall often bear inscriptions indicating the name of the region and the official responsible for the construction to ensure quality control.
The fortress route includes the 'Baekak' section, which requires official identification for entry due to its proximity to the Blue House.
During the Japanese colonial period, significant portions of the wall were demolished to accommodate city infrastructure and tram lines.
The wall follows the natural topography of Seoul's four inner mountains, acting as a physical divider between the historic city center and the outskirts.
Seoul Hanyangdoseong Fortress is an 18.6-kilometer stone wall originally constructed in 1396 during the Joseon Dynasty to define and defend the capital city. The structure traverses four major mountains, including Bugaksan, Namsan, Naksan, and Inwangsan. It incorporates four main gates and four auxiliary gates, which served as the primary entry points to the city for centuries. Sections of the wall showcase varying construction techniques, reflecting the architectural styles of different eras, from the 14th century to modern restorations. The fortress remains an active pathway that provides a continuous corridor connecting diverse neighborhoods across central Seoul. Modern lighting along the wall illuminates the path for evening access, contrasting the historical masonry with the surrounding urban landscape.
