In March, 2015, I spent three days exploring some renowned parts of Barcelona. I visited three buildings designed by architect Antoni Gaudi: Sagrada Familia, Casa Batlló, and La Padrera. All three buildings are declared as World Heritage Sites by UNESCO (United Nations Educational, Scientific and Cultural Organization).
I visited La Boqueria market to see what local people eat. The Barcelona Cathedral in the Gothic Quarter and the skateboarders in front of MACBA showcase the ancient and modern cultures of Barcelona.
