muslims seem to have a history of destroying wherever they go then placing a mosque over it to show their conquest. Haga Sofia, the Temple Mount, and now the WTC Victory mosque (which Bloomy & Gov Krispy Kreme seem to support) are other examples. I read somewhere that there is a mosque in Alexandria Egypt that was being repaired and they found what was believed to be the tomb of Alexander the Great.
Muslims and early Christians are two sides of the same coin in how they regard religious sites.
They didn’t build a mosque over Hagia Sophia. Hagia Sophia was a cathedral that the Moslems made into a mosque and that was later made into a museum. The original building is still there in Istanbul. I have been there and seen it.
