Europe has its traditions and cultural heritage and it strives to protect them. Generally speaking, each region in Europe (not restricted to an independent country) has its own architectural traits and the local legislation is strict in preserving and maintaining its character. That is why European’s cities are so beautiful unlike the anarchy and horrendous architectural fruit salad of some places in Asia!
For that reason, minarets are beautiful when seen in the right context, in Islamic societies / cities!
In Europe, expect to see amazing Cathedrals!
