The main reason for a tourist to travel to Córdoba is to see the massive Mosque-Cathedral.
Locally, it’s called the Mezquita.
Under the Moors, Córdoba became the most important city in Europe, a centre of education and learning.
The feeling inside for me is mostly Islamic. Yet all around Christian elements were installed and built starting 1523 after the Moors were expelled.
It’s a nice balance. Did I mention it’s HUGE.
856 columns. And Christians had many more removed.

Mind blowing. Did you take the overhead shot with your drone? If so, what are the regulations in operating a drone in an area like Cordoba?
