Religions build cathedrals, temples and mosques in order to impress. If someone is prepared to invest so much time and effort it must be true.
They employ the best architects and artisans.
Ceratinly the The Sheikh Zayed Grand Mosque is impressive. I think the name says it all. Someone wanted their name to be recognised. In past times Trump might well have built a cathedral, temple or mosque. Instead he built Trump Tower.
The beauty of this mosque was breath-taking.
