We went to church.
The Santuary of the Madonna of the Rosary is worth a visit – even though the archaeological site of Pompei (right next to the church) is far more famous.
Its impressive 57 meters to the ceiling and amazing craftsmanship and sense of details definitely brings the feeling of being near something divine, and you can actually go up the bell tower (with elevator). Unfortunately we arrived at the tower just as it was closing for visitors, which we learned is 6PM.
A ceremony was going on when we entered the church and we got to experience its authentic atmosphere as locals were joining in for the worship.
