The first few days we spent on the beach, which was my favorite part of the trip :)
We then hit the city to check out the history. We saw the amazing Park Guell, built by Antoni Gaudi (who pretty much built the entire city of Barcelona).We made a side trip to Tarragona to see the ancient Roman ruins. We saw the Amphitheater, which was built around the 1st or 2nd century, and we saw the Roman forum.
