I knew I could have just wandered around Barcelona and seen examples of modernist and Gaudi architecture on my own, but I was interested in learning more about Gaudi and the history of some of the buildings I wanted to see. As a result, I signed up for the Gaudi Tour with SANDEMANs NEW Barcelona Tours. It’s an affordable 3-hour tour through Barcelona, though it actually ended up being closer to 4 hours long.
