You might know that church "opposite" Duomo, Pio Monte della Misericordia , here is the famous Sette opere di Misericordia, painted ca 1607. (The Seven Works of Mercy).
This is one of very top attractions I want to see.
There are at least two more paintings
First the magnificent The Flagellation of Christ up at the Capodimonte Museum. How do I travel to that museum, is it too far to walk from Santa Maria della Sanita, the church with the catacombs?
Second, Palazzo Zevallos di Stiglian in Toledo somewhere, with The Martydom of St Ursula. Have you been to this Palazzo? This only a 5 minute walk from my hotel, so I am very interested in visiting this place.
