Underground Women's Cells
These underground solitary women's cells were quite small. You could not comfortably stretch into a sleeping position in them. They housed females who were fighting for Korean independence.
After visiting the women's cell, I went to the main administrative building. It had some interesting displays about the occupation and "patriotic ancestors who valiantly fought against the Japanese invasion for sovereign independence." The basement included some really creept animatronics displays about torture that the Japanese employed. They also had a special exhibit (entirely in Korean and Japanese) about poetry and letters written by prisoners. Unfortunately, photography was not allowed in that building.
