Even as President Barack Obama brought the debate over the so-called "Ground Zero mosque" to the national level last weekend, Muslim residents of a very different city were launching their own version of the Cordoba initiative. In the real Cordoba:

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.

Until the city was reconquered by Christian armies in the 13th century, Cordoba was a key symbol of Spanish Muslim culture. The Mosque of Cordoba, in particular, drew countless worshippers to the region. If the activists get their way, Cordoba's historical reputation may soon be restored.
