In 2012 we visited the South of Spain and one of day trips was to Cordoba to visit the mosque/cathedral of Cordoba. It’s huge and very interesting because of its history of switching between a mosque and cathedral. Currently the building is used as a cathedral and Islamic prayers are not allowed.
My Canon ultra wideangle came in very handy. One the many Unesco World heritage site we’ve visited in the world. I should make a list one day to see which ones we have been to.
I’ve also noticed when editing these photos that it is hard to keep the lines straight. Especially in such a building with many different lines and using a wideangle lens it is very easy to get crooked lines and distorted perspectives. Not real advice, but keep that in mind.
