The biggest churches in the world: Anglo-Norman eleventh-century cathedrals
In order to understand how the architecture of middle ages and modern intertwined between Christian and Muslim worlds, please check this excellent video [1].It's never ceased to amaze me by the fact that now most of the mosques now look more like Christian's Hagia Sophia and churches now looks more like Muslim Spanish Moors' Mezquita.Also it's often an oblivious fact that Norman also conquered Sicily (after Muslim's cosmopolitan Emirate of Sicily) and obviously they had learnt a lot from the Islamic architecture that they brought and implemented the concepts to Britain and other parts of Europe [2].[1] https://www.youtube.com/watch?v=xvnVi5G5SQA[2] https://en.wikipedia.org/wiki/Emirate_of_Sicily
