As masses of Jews begin intensive preparations for the upcoming Passover holiday, employees at Jerusalem's holy site, the Western Wall, have embarked on a spring cleaning of their own.

Western Wall workers have started to remove the thousands of notes left by visitors in the cracks of the wall - including U.S. President Barack Obama - filled with wishes and prayers.

The notes are removed using wooden sticks dipped in the mikveh, or ritual bath, supervised by the Western Wall's presiding clergyman, Rabbi Shmuel Rabinovitch. They will then be taken for burial, to make room for an upcoming year of written requests.
