Disappointing, I would say. It's one small gallery, literally one room that exhibits at the moment some photógrafs, some garments and some pictures. Then there is one other room with the history (solo Portuguese). And one tiny chapel, that also exhibits some garments.
The cafe is alright, the coffee is below average quality.
It's free, but not worth a extra visit, I say. If you are in the area, have a look for 15min.
