Seoul has a strong contemporary art scene and street art is on display all through the city. New buildings and communities are constructed with art tightly integrated into the design of each building and the grounds. Here's a few great pieces that I run across in my rambles through Seoul and nearby Pangyo.
Art in the streets
Visiting Seoul has been a great adventure and I'll have to come back some time when its warmer and explore more of the city and some of the surrounding countryside.
