The Seoul Museum of History was featuring a special exhibition on a major artery passing through Jongno. Unfortunately, most of the exhibits lacked English explanations, but the historic photographs and street scenes gave a good idea of what the Korean displays were trying to convey.
While not as impressive as the Shanghai or Beijing models, Seoul's model was still quite big. The city is quite spread out in all directions.
The model had too much special effects and not enough lighting to fully appreciate the urbanization.
