Must see IMO. A couple really great rooms. Includes the original doors to the baptistry (what's on there now is a replica). Also includes Michelangelo's Pieta and Donatello's Mary Magdalene.
Visiting as addition to Duomo Cathedral and Duomo Temple. The exposition of original masterpieces from Duomo de Santa Maria del Fiore. In Duomo there are their replicas.
History of the Cathedral and Duomo. I liked the models of the cathedral and Duomo made in wood. The short movies about Duomo and Medici family are worth to see.
The original Gates of Paradise are back on display as of May 2013. They're waiting to build a new museum to house them in original context. Great interpretation of gates opposite.
Só a visita ao salão dedicado à Pietà de Florença já vale o preço do ingresso. Mesmo assim, há todo acervo a ser visitado, o qual inclui relíquias, pinturas, esculturas e artesanias.
