From an architectural point of view the building is a masterpiece, fusing the lower octagonal section with the dome by melding them together with a drum. Internally the drum and dome are supported by the inner circle of columns a mixture of massive rectangular supports with slender round columns between (in the foreground can be seen the rock itself on which Abraham built an altar and attempted to sacrifice his son, Isaac):-
Here is rather a similar but more striking photograph by Martin Gray the photographer of sacred sites throughout the world, who has captured the sun streaming through the windows on to the rock itself; it, too, shows the architectural details with slightly more of the decorative themes.

As with all Moslem buildings, the interior decorations are exquisitely beautiful and entirely geometric in design with no representation of living things, as is consistent with Islamic law. A wonderful example of this can be seen in the interior of the dome itself:-
