The Amiran hotel 49 Khakikat Street, has got facade with an historical iwan-like look.[br]The spandrel above the entrance has got a pattern with 10- and 5-pointed stars, a nice finger exercise before starting the real historical work.

It's a pattern from the fivefold system, containing decagons, pentagons and a hexagonal barrel [br](cfr Bonner Fig 227 A en B). [br]The pattern creates dark colored 10- and 5-ppointed stars that attract the attention.[br]Amidst of them are lighter, irregular hexagons and dark dodecagons seemingly two pentagons melted together.

In next applet you can follow the construction of the patters.[br]Even without perspective correction you can clearly see that the hexagons between the stars are irregular.
