The tiny Cappella Niccolina, which was built as a private chapel for Pope Nicholas V (r. 1447-55), is located in one of the oldest parts of the Palazzo Apostolico in Vatican City. In historical documents, the chapel is described as 'parva et secreta' (small and secret).
Pope Nicholas V commissioned the great Florentine artist Fra Angelico (c. 1395-1455) to paint the frescoes in the chapel; they depict scenes from the lives of St. Stephen (upper level) and St. Lawrence (lower level).
