Bow your head, say a prayer and perhaps even light a candle in Oria Cathedral. This grand place of worship may not be open all day, so check ahead for times if you'd like to see inside.
When you've finished at this principal church in Oria Historic Centre, why not check out Castle of Oria, Basilica Minore Pontificia Santissimo Rosario, and Crypt of the Mummies? They're close to Oria Cathedral and also popular with tourists.
