It is said that it was the earliest prison, had also been a barracks, belongs to the Museum of historical relics. Because it is not the destination of the tour group, there are not many tourists. But we can see that Australian primary school students, under the leadership of teachers, queue up to visit the whole class, which seems to be an educational base. The copper well covers outside the museum are cast with the front architectural drawings and brief instructions of the museum. The Museum has a unique design for a section of the south wall of St. Mary's Church. The whole glass is embedded in the wall, with Museum instructions carved on it, as well as tables and pots embedded in the wall. It feels like a room, and the design is very ingenious.
