On Chanukah we celebrate the miraculous defeat of the Syrian-Greeks by the Chashmonaim. Part of the miracle was that the Jews found a single flask of oil still sealed with the mark of the Kohen Gadol. Opinions vary as to where this flask was actually discovered.
According to one view, it was found in the access tunnel beneath the Altar! See this post for more information.
