This photo is of the beginning of one of the routes (which we didn't follow) - the Hebrew reads "The Ghosts' Quarter" (in imitation of the names of the quarters in the Old City - e.g., the Jewish Quarter, or the Armenian Quarter).
This was a display at the end of the road that runs through the Armenian Quarter.
This was a giant, lit-up, sculpture of a woman, close to Zion Gate.
The next few photos were of an installation on the inside of the wall surrounding the Old City, close to the parking lot in the Jewish Quarter. The letters are in Hebrew and Arabic, both spelling out the word "light" in their respective languages - or in Hebrew and nur in Arabic.
