The north iwan along the inner court has got a spandrel with a geometric pattern. Apart of a text on top this is the only decoration.[br]As the spandrel of the main entrance, the patterns is generated by decagons, but it looks completely different.[br]Although it looks more comples, the construction is simplier: it's jus a tiling of decagons and ties. [br]The complex look is due to the elaboration of the lines as a braid and the colouring of the forms in the pattern filled with multicolour floral motives.
