The church of Holy Trinity, born as an Oratory in the Seventeenth century and later consecrated to the Holy Trinity of the Poor n 1735, when it was built as a parish by Bishop Felice Leone.

Destroyed by the earthquake of 1805, rebuilt and again damaged by the seism in 1980, it was closed and is now home to theology courses. The prestigious painting of the Trinity by Solimena from 1672 was saved at the Superintendence.
