These are the products of minds that refuse to be Eurocentric.
These days you see even respected Yoruba Obas building Hellenistic-style palaces, and I shake my head.
You can only create architecture like this by believing in yourself and embracing your own essence, culture, and history, not by assuming that white Europeans are somehow superior.
If you accept that other people are inherently and culturally superior, you will always try to copy their templates, whether they fit your reality and context or not. You will never generate original, distinctive ideas of your own or improve on any of the legacies of your ancestors.
