Seville's cathedral - something for my religious friends

This has to be one of the most decadent churches I have visited. It was previously a mosque which after the reconquest was turned into a cathedral. It is huge and very ornate. Elements of both islamic and christian cultures remain today.

At first it is very confusing to see such a combination in existence. My first two pictures show the cathedral inside and out, and the second two show elements of the mosque still present today.

It is also the site of Christopher Columbus's tomb.
