Cave of the Patriarchs

Photo is courtesy of "Tbass Efendi" who published it on Flickr. There is a row of six pointed stars on the outer arc which are created by the curved lines of the pattern. In the center there is an eight pointed star. To me this whole ornament looks like an eye that watches the Muslim believers while they pray.
The Cave of the Patriarchs serves both Muslims and Jews and this photo is an opportunity to focus on its Muslim part.
