Focus on Niccoline Chapel and explain the abstract.
The Niccoline Chapel (Italian: Cappella Niccolina) is a chapel in the Apostolic Palace in Vatican City. It is especially notable for its fresco paintings by Fra Angelico (1447–1451) and his assistants, who may have executed much of the actual work.  The name is derived from its patron, Pope Nicholas V, who had it built for use as his private chapel.
The chapel is located in the Tower of Innocent III, in the most ancient part of the Apostolic Palace. The walls were decorated by Fra Angelico with images of two of the earliest Christian martyrs; the upper level has Episodes from the Life of St. Stephen, and the lower one Scenes from the life of St. Laurence. The vault is painted blue, decorated with stars, and features figures of the Four Evangelists in the corners. The pilasters are decorated with the eight Doctors of the Church.
The chapel is not included in the usual tourist visit, but can be seen by special pre-booked groups.
