I'll buy that.
Expect that if there are more excavations on the site then a jumble of bones and perhaps even bodies that would have been buried in coffins should emerge. If there are very few bones from the site - i.e it was disturbed regularly over the centuries after the monastery was demolished, my "they knew it was there all along" conspiracy theory holds water!
