According to our guides, the federal building behind the station needed a mail room and sadly re-purposed most of the original bus station. What remains is an isolated, "imagine if you can", single room with photo exhibits, a few pieces of artistic expression and a video booth for recording your own human rights violation experience or watching/listening to another's. There is a small gift/souvenir counter and that pretty much sums it up.
Outside, there is a great story board that does a nice job of explaining the sequence of events. It is worth looking at.
The museum hours are (Friday & Saturday noon to four only). Admission is $5 per person.
