> Good question: Claims that is is the burial cloth of Jesus Christ are fraudulent.

Maybe fraudulent is a little bit strong. The different analysis done (not the C14 one, which proved to be unreliable) indeed show it may be around 2000 years old or so. Now, we have no way of proving that the person who was wrapped in the Shroud is actually Jesus or not, while there are some similarities in the injuries described in the Bible and the blood stains locations on the Shroud. I think even the Church itself does not recognize it as being 100% authentic.

So, "we don't know", is probably close to the truth than "fraud".
