Jerusalem is kind of a blur now, but I can tell you that 1 day is not nearly enough time. You really need 3 or 4.

For some reason I thought the city was divided in half by some sort of monstrous wall that separated the Arab side from the Jewish side. This is not the case. The wall does exist, but its visible to the east of the city, carving Jerusalem out of the west bank. The Arabs in the city are generally citizens of Jerusalem, but not Israel. I think they are free to go where ever, just as we were free to walk through their areas. The city in general is pretty dirty, but the east side is especially filthy, as most Arabs boycott Israeli government services, such as trash removal.

Many of the Christian sites are in Arab areas. They revear these sites, and are glad to have Christian tourists. In fact, because it was Christmas, they would have been closed had they not been under Muslin jurisdiction.

We did a walking tour of the "12 stations of Christ's suffering", which are places throughout the city where legend has it that different events in the crucifixion took place. Many seemed to be in random places, for instance the middle of a crowded market a sign in arabic would mark were Jesus collapsed under the cross.

The one location they know to be accurate is the crucifixion site, The Church of the Holy Sepulcture. Four different churchs bicker for control of this shrine; Greek, Catholic, Ethiopian, and Armenian, and have basically marked off different areas they control. The styles between these areas varies tremendously.

The original monument is impressive, built around 300 AD by Constantine's mom. The Crusaders built an even larger monument around that, so that what is there today is a church within a church.
