It can be interesting to look into different belief systems. A visit to Basilica di S. Alfonso M. De Liguori is an excellent way to get to know a part of the local culture.
When you've finished exploring this house of prayer in Pagani, why not make your way to Shrine of the Virgin of the Rosary of Pompei, Pompei Amphitheatre, and Parco Regionale dei Monti Lattari? They're near Basilica di S. Alfonso M. De' Liguori and also a hit with many tourists.
