In order to enter the Dome of the Rock and the nearby Al Aqsa mosque, we had to remove our shoes and refrain from laughing, holding hands or taking pictures. The floors were covered entirely in prayer carpets which my sister noted smelled like dirty socks. (I didn't notice).
Here is a closeup of our group photo. The couple in the background are our guide's daughter and son-in-law who joined us for the day.
