Oddly enough, this is the grounds of a prison, the actual holding area off to the right there. Korean insurgents were held here after they proclaimed some sort of independence from the Japanese against their colonial masters. You can walk into the cells, only to realize that some of them are too small to even sit.
All this and yet it is one of the most peaceful parks in small, full of families and laughter and school groups touring the facilities. I used to live about three minutes from here, on foot, off to the left. We moved about a year ago and I miss it like it is gone forever, but people still congregate here, still laugh and walk and play with their children, their pets, their free time.
I think I will miss it more when I leave the country soon.
