The orphanage and Church of Mercy were built between 1592 and 1607 by the congregation of the Oratorio dei Bianchi. The institution took in abandoned children, and the new name of the church, 'dei Turchini' (of the Azures) instead of 'dei Bianchi' (of the Whites), referred to the clothes worn by the children. In the conservatory next door, children studied music and singing, and among them was the great Giovanni Paisiello. The conservatory then merged with San Pietro a Majella. Completed in 1595, it was then extended in 1630. It is typical of religious buildings of the counter reformation. The chapels were decorated by Battistello Caracciolo and Filippo Vitale as well as other figures from the 17th-century Neapolitan painting circles.
