Excerpt:
Muslims in Spain are campaigning to be allowed to worship alongside Christians in Cordoba Cathedral -- formerly the Great Mosque of Cordoba.
Today, at the original Cordoba mosque in Spain, there is no call to prayer, only the ringing of church bells. That's because the former mosque is now a working Catholic cathedral, performing a daily mass.
It's been a Cathedral since Spain's Christian monarchy conquered Cordoba in the 13th century and more than a million visitors walk through its doors every year.
