This is just such a funny collection of things, looks like they throwed everything together that they could find that has something to do with history. The museum is worth a look but the real thing to see is the Igreja De Santo Antonio which you can enter through the museum. Don't remember if you had to pay entrance for the museum or only for the church. The church was build in the 18th and 19th century and is very extravagant in its decoration. It has some really nice paintings on the wall depicting the "Miracles of Saint Anthony". When I was there I overheard a guide explaining to this Irish couple that there was an English guy high up in the military if I remember correctly that turned his back on the Church of England and became a Catholic so he could be buried in the church. I don't know if he made it up to charm the Irish but it is an impressive church non the less.
