All but four of the churches on the island are Catholic. We toured St. John’s Cathedral, which houses two Caravaggio paintings and the only Caravaggio in existence that was signed by the artist. "The Beheading of St. John the Baptist." It is truly one of the most awesome works of art I’ve ever seen. I could have lingered there for the day if I didn’t have to give way to others wishing to be in the presence of this masterful piece of art. The church itself was so beautiful and so ornate that it brought tears to my eyes.
The carved stone walls and painted vaulted ceilings are a tribute to the life of St. John and designed by the artist Mattia Preti. This cathedral also houses the tomb of the founder of Valletta, Grand Master Jean Parisot de la Vallette
