The Grail supposedly was kept under the temple in Jerusalem and then disappeared at some point in the middle ages

Why would the grail be kept under the Temple? Do you mean the Jewish Temple? Why would they keep the grail there?

I don't remember the details. That's the one relic that plain and simply disappeared in the Middle Ages. The legend is that the Knights Templar found it and kept it in a secret room in Jerusalem under the temple. Whether it was the Jewish temple or their own I'm not sure. The records are very spotty.

Why would the grail be kept under the Temple? Do you mean the Jewish Temple? Why would they keep the grail there? The temple was built upon the rock of Abraham where he nearly sacrificed his son. This is an extremely holy site and appropriate for another holy relic such as the Holy Grail.
