you probably would think I'm crazy but one of my favorite things is to sightseeing churches.. I love what you share here with us but you need to remember that every single church have something special to share. My fav is in my hometown (I'm not super religious person I'm mort Art Lover!) 
Love all your shots, it was a pleasure to get known better this place with u!
Looks beautiful, but I'm telling you La Sagrada Familia has to be seen.
