Chen Danqing has a chapter focusing on St. Mark's Church. He says that if there is only one day in Florence, he advises not to go anywhere, just to St. Mark's Church. There are religious paintings (wet murals) that best reflect the medieval (13th - 15th century) and reflect the painter's devotion to God. I like this place for spiritual refreshment very much. Angeloco, the master, has closed himself in the monastery for nine years and completed murals in many rooms on the second floor. It is very beautiful and quiet. It is painted as his name (the name of the master angel ); and the tone is elegant and pure. PS: There are not many tourists there. They are very clean. They can slowly and carefully appreciate the religious painting gem of the Middle Ages - wet murals.
