One of the many patterns o the side wall of the mosque is a weave pattern of perpendicular rectangles grouped by four with a tiny square in the middle. [br]In the rectangles you can read [i]Alahu akbar[/i] (God is the greatest).[br][list][*]The pattern is created by two overlapping sqares, forming the basic rectangle.[/*][*]Perpendicular to the first rectangle a second, identical rectangle is placed.[/*][*]Rotating these rectangles creates the unit repeat of the tiling.[/*][/list]
