First of all it is Iceland. I've been there a few times and I was very impressed. Most of all I liked the village of Vík and the surrounding landscapes. The oceand and the beach with black basalt sands are amazing in this place.
Just an example from network
I also made some similar photos and attached it on the wall of my room. I will share it as soons as possible, fortunately I have a good printer for this.
Seville in Spain for European architecture.
Plaza de Espana, Giralda, Seville cathedral, Real Alcazar.
Plus the tapas is fantastic! And flamenco dancing.
I recommend staying at Casa de Judeiras. Nice hotel. It's actually a converted residential neighbourhood with the side alleys between the houses still intact. And one of the few places in Europe with banana trees.....
