 These early conservatories were "Santa Maria di Loreto", "Pietà dei Turchini", "Sant'Onofrio a Capuana", and "I Poveri di Gesù Cristo".They enjoyed a considerable reputation as training grounds not only for young children to be trained in church music, but, eventually, as a feeder system into the world of commercial music once that opened up in the early 17th century.Santa Maria di Loreto was built in 1535 and was the original conservatory in Naples, coming at the beginning of the Spanish expansion of Naples under the city's most famous viceroy, don Pedro de Toledo.
