In Northern Israel, near Mt. Meron, is a location marked as the holy tomb of Mordechai and Esther.  This is not the only location noted as the Kever of Mordechai and Esther, another is in current day Iran but historical Persia, the location of the Purim story.  Here’s the one in Israel…

Down a hill is an entrance to a small cave and the remains of a kever with the entrance blocked.  Is this the holy resting place of Mordechai and Esther of the Megillah?  Perhaps, perhaps.

Commentor mochinrechavim added, "Mordechai returned with Ezra to Eretz Yisroel, so this location makes sense as I can't imagine Mordechai returning to live in Persia. Esther however was a queen and I cannot imagine it would have been possible to leave to be buried until the redemption like Yosef. The Jews during Purim were saved, but not redeemed."
