Muqarnas مقرنس dome with  orb and column

This muqarnas composition is made of a number of complex muqarnas مقرنس forms which all are joined together in a single continuous surface that has no gaps or overlapping elements. Topologically it is a cylinder or half of a torus (donut). Most of the elements display radial symmetry except of the 'column' supporting the orb and the outermost part of the ceiling just above the outer supports. They display chirality (left or right handedness). So the structure as a whole could have a mirror image that would be distinct. Minus those two elements, the mirror image would be identical.
