Visit the museum for Fra Angelico paintings and frescoes, it is not far from the Galleria dell'Accademia. There is his famous 'Annunciation' that you see the first thing as you enter the first floor where the monk cells with Fra Angelico frescos are. The paintings on the ground floor are stunning, blend of Gothic and Renaissance styles, were striking me with emotional expressivity. Highly recommend the visit!
Entrance fee is 7 Euros, closed on Mondays (with some exceptions, read below) as many museums are. Opening times are a bit complicated but worth planning around them: Tues–Thurs 8.15am–1.50pm, Fri 8.15am–6pm, Sat 8.15am–7pm; also first, third and fifth Mon of month 8.15am–1.50pm, and second and fourth Sun of month 8.15am–7pm.
