The main attraction is the "Shabou and Central Watchtower," consisting of five buildings on the premises. The building was constructed in 1912 and you can see what it was like when it was actually used as a solitary confinement cell. The entire building is dimly lit, and it's hot in the summer and cold in the winter, so you can feel how harsh the living conditions were for the prisoners at that time. You can even step into the watchtower, making it a great spot for taking photos.
