Florence on Mondays. What''s open?

HI. We also will be there on a Mon. and had planned on the duomo and its dome. But Rick's Tuscany and Florence book shows that quite a bit is still open, some of them though only on certain Mondays. Duomo Museum Bargello Museum of San Marco Medici Chapels Duomo and Dome Galileo Science Museum Santa Croce Church Church of Santa Maria Novella Brancacci Chapel San Miniato Church Campanille Baptistery Casa Buonarroti Piazzale Michelangelo There might be more but this is just what I saw. I would really suggest getting RS's Italy book it has so much info on these things.
Buon viaggio

sounds like there is still plenty to see. I'll have to get his book. Thank you.
