The four great Venetian Ospedali (Ospedali Grandi, also referred to as the Ospedali Maggiori) - the Ospedale della Pietà, the Ospedale degl'Incurabili, the Ospedale di Santa Maria dei Derelitti, and the Ospedale di San Lazzaro dei Mendicanti - were charitable hospices, which provided a wide range of services for the needy of Venice. They are most famously recognized for educating select female pupils (called figlie del coro) to professional levels of musicianship and attracting many European tourists to hear their all-female ensembles perform religious services and special concerts throughout the seventeenth and eighteenth centuries. The musical training in the Ospedali Grandi is often thought of as a precursor to the training in European conservatories of the 19th century.
