We walked through the streets of L'Eixample past many stately homes. The area was Barcelona's 19th century answer to overcrowding in the medieval city and L'Eixample really just means the Extension. La Pedrera an office block and apartment was built by Gaudi between 1905-10 and has an uneven grey stone facade which curves around the block. The ironwork on the balconies looks like seaweed rippling in the ocean, it is very organic and still today is a very unique building. Further along is Casa Batllo. This building is the stuff of fairy tales. We did a tour of Casa Batllo and it was well worth it to see the detailed interiors of this privately owned house designed by Gaudi. They say that if Sagrada Familia is his master symphony then this is his whimsical waltz. Inside it is pure fantasy with no straight lines or right angles. We ended the day with a visit to Parc Guell where Gaudi turned his hand to landscape gardening with amazing results. It was a lot of fun and reminded us of Disneyland. It sits up high on a hill and has great views over Barcelona and out to the blue waters of the Mediterranean.
