Seoul is a capital where glass supertalls and Joseon-era rooflines share the same sightline — hypermodern finance beside tiled courtyards that refuse to leave. This poster reads that tension as geometry: navy and gold arches frame the Lotte World Tower needle, N Seoul Tower watches from Namsan, and hanok rooftops anchor the foreground like proof the old city never fully moved out. Rank 18 in the Suncities collection, it is illustrative travel art with texture and pattern doing the persuading — not a tourism slogan.
