See those two guys on chairs. When I went up to look for signs they shooed me away. What is this building, I asked. ALL, one guy replied, ALL this, (taking my map and drawing a line around the whole huge Temple Mount area) ALL this is Al Aqsa Mosque. ALL this. They were certainly making a point.
On the map btw, that building here is called Al Aqsa Mosque and the other buildings have their own names.
