We did not just play with the pigeons for the entire afternoon (Sunday).We also visited Placa de Catalunya. We walked all over. We stopped often for the children to play to keep them distracted. They did not get a chance to notice just how far we walked, before taking the metro back. Plaça de Catalunya is a large square in central Barcelona that is generally considered to be both its city centre and the place where the old city and the 19th century-built Eixample meet.
