Alhambra, Patio de los Leones

In this simple form the pattern occurs as a pair of wooden ceilings in the middle of the east and west galleries of the Patio de los Leones, behind the east and west pavilions, respectively. A single square of this pattern, with 12-stars at the corners and centre, forms the underlying basis of the large mosaic panels in the central alcove of the north wall of the Salon de Comares. Each rectangular is basically 9 x 5 such squares.

• All the internal angles of the constituent polygons are a multiple of 15°.
• Contains one regular 8-pointed star polygon with vertex angle of 90°.
• Contains one regular 12-pointed star polygon with vertex angle of 60°.
• There are three non-regular reflective tiles (including one kite).
• The tiling satisfies the interlace condition and has no finite interlace and two infinite interlaces with straight cross-overs.
