This modern art gallery exhibits works from the 19C and 20C arranged according to themes or trends such as neo-Classicism, Romanticism, Purism, historical painting, portraits and landscape painting. Among the gallery's most notable possessions are an exceptional series of works by the Macchiaioli, a group of painters working around 1860 to 1871 (Room 18). This Impressionist style of painting was a reaction to the rather cold academic style which preceded it.
