We were a corporate group of 10 people that enjoyed this walk together. It was nice to get to know Barcelona in another way through the walk "ReThinking Cities". The insight to the history and how things are planned and developed up until today was very interesting. To learn about the philosophy for the area today and how they consciously put together technology, architecture elements, economic and environmental systems and binding together the old and the new is inspiring. Our guide Jordi shared his knowledge and passion for his profession and we had a great time together. I would absolutely recommend this walk and especially if you have some interest in architecture and engineering.
