At the monastery of San Marco, Fra Angelico and his assistants frescoed paintings in the cells of the monks and their community rooms. The monastery of San Marco is a convent in the Italian city of Florence. The monastery was reconstructed in its current state in 1437, while the decorations of the walls started in 1439. The decorations were carried out by Fra Angelico (or officially named Giovanni of Fiesole) and his assistants. The frescoes he painted are said to prove his respect for his god and his love for humanity.
