Semana Santa (Holy Week) is one of the most spectacular events that take in the city of Sevilla. Despite the obvious religious implications of this celebration, you really do not need to be a devote Catholic to enjoy it.
The tradition of carrying floats (pasos) representing the passion and death of Jesus Christ dates back to the late Middle Ages (around 1350).
You have to belong to a brotherhood to be able to march with the images in an outfit that for Americans may seem infamous (to say the least), but which precedes by centuries that hateful organization and has nothing to do with it.
Myriads of people accompany the images of Jesus Christ and the Virgin (each one has a different name, but they all represent the same Virgin Mary).
The newspaper Diario de Sevilla makes a comprehensive coverage of the event.
