This picture is of a fountain that has been created from a spring from where Mary (mother of Jesus) supposedly drank. One interesting note - the monument to Mary's spring was originally some sort of Christian monument, perhaps a church. However, after most of the Christians were forced out of Jerusalem (I forget the years), the place (as were most Jewish and Christian holy sites) was converted into a Muslim mosque. Though you can't see it in this picture, right above the fountain there is a minaret, from which the Muslim call to prayer takes place.
For ages, this fountain (and spring) were renowned for the quality and freshness of their water. However, in recent times, the water has been contaminated by sewage, and is no longer drinkable. If you look closely, you will see trash along the bottom of the fountain. The red Hebrew graffiti on the wall says something to the effect of: This holy water runs into the sewage.
This phenomenon of holy or religious sites being defiled by trash seems to be a theme in this neighborhood. Check out this sign, which reads: This is a Holy Place; Keep it Clean! -- and the pile of trash underneath it. We saw this sign on the road between Mary's spring and the Church of the Visititation (see next pictures).
The Church of the Visitation: This church is built over the traditional home of Elizabeth and Zacharias, and is built in memorial of Mary's visit to Elizabeth while the two women were pregnant with Jesus and John the Baptist, respectively. (See Luke 1:39-49.) The prayer that Mary is said to have uttered ('My soul exalts the world') is from Luke 1:46-56, and on the walls of the complex it is recorded in over 41 languages (thanks Lonely Planet).
