Wether you are a spiritual person or not, you should visit Sevilla at Easter at least once in your life. It’s shocking and impressive but most of all, moving.
It’s normally really crowded, so you have to choose very carefully where to stay if you want to have a nice view. The city smells of incense and orange blossoms and it’s full of art. The statues, most of them Baroque, are simply beautiful, the canopies are incredible and carefully decorated with flowers and the atmosphere is outstanding.
Regardless your opinion about religion, it’s undeniable that you can feel the energy and the profound beliefs of some people. You can literally see faith in their faces.
