Jay and I went hiking in a mountain called Namhansanseong. Try to say that ten times fast without messing up. The day was a bit cloudy and not too hot, which was actually nice since it can be pretty hot and humid in Seoul in the summer time. The bottom picture is a part of the fortress that was built on the mountain and used first during the Shilla Dynasty (around 600) to defend Seoul. Yes it has been rebuilt.
