St John's Co-Cathedral contains eight rich chapels, each of which was dedicated to the patron saint of the eightlangues (or sections) of the Knights. The inside of the Cathedral is in sharp contrast to the facade as the extremely ornate interior decorated in the height of the Baroque period. The inside was largely decorated by Mattia Preti, the Calabrian artist and Knight. Preti designed the intricate carved stone walls and painted the vaulted ceiling and side altars with scenes from the life of St John.
