Suleiman the Magnificent's fountain "sabil" on Hebron Road (technically the dam at the southern end of the Sultan's Pool). Built in 1536. The entablature above the sabil is not original and was added by the editor. Mishkenot Shaananim is in the background.
It looks like the sabil at the southern end of Sultan's Pool with Yemin Moshe in the background
This is the southern end of Sultan's Pool with Mishkenot Sha'ananim in the background, looking towards the west.
Here's a photo of the fountain, and of course that's Yemin Moshe in the background. http://www.biblewalks.com/Photos21/SebilHebronRoad.jpg In those days, the pool probably was still used for water. Here's a photo of the pool with water in it, rather than seats for concerts! http://blog2.bibleplaces.com/uploaded_images/dcd5de447251_6DB6/SultansPoolwithStAndrewsChurchmat12447.jpg The fountain is at the top of the wall, in the center.
I wouldn't say the windmill was edited out of the picture. It appears to me that the photo was simply over-exposed, and as a result of that the windmill washed out in the photo. If you look closely you can see the bottom left edge of the windmill and the top of the dam next to it.
