We will visit the oldest parts of Bilbao, nowadays its most international and controversial neighbourhood. We will see the "doors" of the iron mines that brought money and immigrants to Bilbao, the places where the prostitutes offered their bodies to these workers, the bars where the ETA terrorist group has its roots or the old Catholic churches converted into rock temples. This is the type of tour no guide will ever offer!
This is they type of visit tourists don't ever have the opportunity to make. It's the best way to know Bilbao from a more real perspective: how it became a powerful business center, what problems that generated and how recent political events have changed the shape of the city.
