Established in 1927, this building was constructed by missionary Seo Ro-deuk (Swinehart) of South Presbyterian Church, who majored in architecture, and was funded by Mrs. Winsborough’s birthday offertory. The building exhibits middle-corridor type with left-right symmetry, and a small protruding entrance porch is impressive. Above this entrance are triangular gable roof and Tuscan Order cylindrical pillar to support the roof. These are unique features that cannot be seen in other school buildings.
