I don't know anything about Chiesa Santissima Trinita, but I want to tell something about the Forza d'Agro town. we came here to eat at "Trattoria Anni 60", which is 100% recommended, and we came, when the kitchen was closed. so we had one hour of free time. walking around the town within narrow streets was very interesting. we met just a few tourists. very interesting, calm, small town with amazing views to have a walk!
