Placa de Catalunya is perhaps the major square of Barcelona. It is located in the centre of the city, where the old town and the Eixample district meet. It was set up around 1900 after the medieval city walls were demolished at the end of the 19th century. The square is very large and connects several important streets and avenues of Barcelona. At the time of visiting, in June 2011, student demonstrations were taking place on the square.
