Pope Benedict XVI has visited Muslim and Jewish holy sites in Jerusalem.
He celebrated his first Holy Land mass as pontiff in Jerusalem's Valley of Kidron, between the Mount of Olives and the walls of the Old City.
Many Christians believe this is the Biblical Valley of Jehoshaphat where God will sit in divine judgement at the end of time.
The pontiff was greeted by hundreds of cheering pilgrims.
This was the first mass the pope had celebrated since arriving in Israel yesterday at the start of a five-day visit that has already taken him to sites sacred to Jews, Muslims and Christians.
Earlier, he visited the Dome of the Rock, whose huge golden cupola has become Jerusalem's main distinguishing landmark, taking off his red shoes before entering the al-Aqsa mosque.
He was welcomed by the Grand Mufti of Jerusalem, Mohammed Hussein, who urged him to work to end Israeli 'aggression' against Palestinians.
The Pope went to the Western Wall, also known as the 'Wailing Wall', where he deposited a written prayer as is customary.
It reads, in part, 'God of Abraham, Isaac and Jacob ... send your peace upon this Holy Land, upon the Middle East, upon the entire human family'.
