Not a traditional museum, but excellent if you like or want to learn about nativity scenes and processional statues (pasos de Semana Santa). The museum has one of the best Neapolitan nativity scenes in the world (huge and with amazing artistic detail), two Spanish nativity sets, a complete collection of procession statues for Good Friday (a Catholic festivity remembering the crucifixion of Christ), and some models and explanations on how images are designed and executed. A very specific museum, but excellent in its genre. The museum is partially situated in a church so you get as a bonus a look at a pretty amazing church.
