In the third floor is the recently restored Church of the Real Monte Manso di Scala, built atop the famed Cappella Sansevero.
For these purposes the charity acquired the present palace in 1654 from the Principe di Scanno, Girolamo d’Afflitto.
Manso in 1611 was also one of the founders of a literary humanist group, Accademia degli Oziosi (Academy of the Idle) in Naples.
The palace and the seminary archive suffered pillaging during the Napoleonic Wars, and was abolished in 1820, although the charitable foundation continued to exist even to today.
The church had been closed since 1959, and suffered more damage, specially in the maiolica pavement, choir, and ceiling, during the earthquake of 1980.
