We continued to hike upwards through the Ihwa Mural Village. On one side of more stairs was this Black & White mural, contrasted beautifully against the blue sky.
On the other side was Seoul's distinctive fortress wall, which was originally built in 1396. The wall spans 18.6 km and was built in 30 years. Parts of the wall have since been restored, while other sections were torn down to make way for modern construction.
At the time it was built, the wall demarcated the outer limits of Seoul. From the many high-rises and skyscrapers now lining the horizon, it is quite apparent that the city has greatly expanded since then.
