There are a number of myths and traditions about the vessels of the Temple. A Jewish one has them hidden under the Temple site. It's been said that Muslims sealed up that tunnel so they could not be found. Interestingly, there is a radical Orthodox group of Jews who want to rebuild the Temple on the site of the Dome of the Rock. They have been copying some of the temple implements and searching for the perfect "red heifer." They receive support from a few Protestant Fundamentlists that would also like to see the restoration of the Temple.
