Gaudi's work, which has been described as "Catalan Modernisme" is supremely original. Apparently he was inspired by a nationalistic search for a romantic medieval past and there are elements of medieval and surreal styles in a lot of his work.
Below are pictures of Casa Batllo. I fell in love with this Casa the minute I laid eyes on it because it looked like a house out of a fairytale. Later when I was reading up on the house I discovered that this apartment block was designed to symbolise the legend of St. George killing the dragon, whose scaly back arches above the main facade.
Facade: It is said that when Salvador Dali saw the curving walls and windows of Casa Batllo he observed them as "representing waves on a stormy day". Because the spindly columns were sometimes compared to tibias, Casa Batllo was also called "House of Bones"
The Main Drawing Room: "One side of this room is formed by stained-glass windows looking out over the Passeig de Gracia. The ceiling plaster is moulded into a spiral and the doors and window framed undulate playfully."
The interior skylight at Casa Batllo...you can't tell from this photo but the blue gets more intense as you travel upwards. This is so that the intensity of light is equal no matter which floor you go to. Gaudi was a genius!
Attics: Don't the arches give one the sensation of being inside the skeleton of a large animal?
Some people say Gaudi created Casa Batllo after reading Jules Verne's "20,000 Leagues Under The Sea" and wanted the house to appear as though it were under water. In this case, the mosaic pattern could easily pass for a colony of brightly-coloured molluscs.
One of the most talked-about features of the house is the Dragon's Back and Cross. The Cross was made in Mallorca but was damaged in transit . Gaudi apparently liked the cracked facade and refused to send it back for repairs.
