Tried this place at night a few weeks ago but didn’t have the nerve to go in but felt like we had to go back. Went back during the day and I’m so glad we did! Such an interesting place to explore, most of the building is well lit but some other parts like the cells were in complete darkness which was very eerie but interesting to see, luckily we had tourches. Didn’t see anyone else but lots of evidence of people being there in the past from grafiti and some damage but everything is pretty much still in tact. Well worth a visit.
