Sadly, contemporary architecture does not tend to place a lot of emphasis on Ceilings.
Cost is probably a contributing factor and building owners may prefer to enhance aspects of their buildings which will be more readily eye catching.
The images below demonstrate the structural and artistic intricacies employed in a very few of the many historically significant and truly beautiful ceilings around the world. That these architectural marvels were built with none of the modern tools and equipment of today, makes them even more impressive.
All of the images indicate their architectural design was developed to the greatest degree of originality and are mind bogglingly rich with relief and painting.
The architects of many historic ceilings (particularly in Iran) employed a fractal design concept (geometric design repeated at ever smaller scales to produce irregular shapes and surfaces which cannot otherwise be created via standard geometry).
It is a pity that works of art of such calibre are only on the ceiling, particularly that considering many people have probably passed them by over the years without realising the beauty of what was above them.
