The Museo del Novecento sits in the former Leopoldine convent on Piazza Santa Maria Novella — 15 rooms of 20th-century Italian art with a loggia that frames the Duomo like a painting. De Chirico's metaphysical squares. Morandi's silent bottles. Guttuso's political fury. Fontana's slashed canvases. The 20th century of Italian art, chronologically arranged, €9.50, and almost empty because everyone is at the Uffizi.
Highlights: De Chirico — Piazza d'Italia series. Morandi — Still Life (bottles and boxes in grey-beige — the most Italian palette). Marino Marini — Horse and Rider bronze. Alberto Burri — sackcloth paintings (arte povera precursor). Renato Guttuso — political realism. The loggia: Open terrace on the 2nd floor with the Duomo dome, Giotto's campanile, and the Baptistery filling the view.
