At a glance
A place worth remembering
One courtyard pattern, an eight-pointed star
MIT Tiling Search analyses a pattern from the courtyard of the Mustansiriyya Madrasa as a tiling that satisfies the two-colour condition and contains a regular eight-pointed star polygon. All internal angles of its polygons are multiples of 45 degrees.[1]
Brick and lime at the Abbasid Palace
Iraq’s heritage submission to UNESCO describes the Abbasid Palace as built of brick and lime.[2]
Light above the As-Saray gateway
The same submission describes the As-Saray gateway’s facade of successive arches, an inlay of copper, brick decoration and a small dome above the gate to bring in light.[2]
