Alhambra, Fachada Solemne

The graphic is developed from a ceramic mosaic bordering both doorways in the south wall of the Mexuar Patio, the Fachada Solemne. The pattern has coloured interlace bands of various colours - black, brown, blue, green and purple, against a white background. It resembles the much more elaborate dados round the walls of the Sala de las Dos Hermanas. It seems that the Mexuar Patio pattern originally extended down to ground level, forming a dado across the width of the south wall, but the dado has now been replaced by more modern dados of small square tiles, which look rather out of place in this setting.

• The symmetry group of the tiling is *442 (p4m).
• All the internal angles of the constituent polygons are a multiple of 45°.
• There are 22 non-regular reflective tiles and 13 tiles with no mirror image.
• The tiling does not satisfy the two-colour condition.
• The tiling is not edge-to-edge.
• As drawn, contains about 566 polygons.
