one of the gaudi houses
Casa Milà, also known as "La Pedrera" (Catalan for 'The Quarry') is one marvelous place.
Antoni Gaudì built this six-storey house in Barcelona between 1905 and 1907, creating a standing masterpiece of Modernism.
Entering the building takes the visitor in the inside of a living body, made of stone but capable to pass the strong impression of breathing, infused with a special kind of life.
More about this can be found in Wikipedia.
Here is a sight of the inside of Casa Milà, the inside of the flat open to the public.
A beautiful example of art.
Getting inside la Pedrera is already a breathtaking experience in itself. Looking at the sky from its courtyard makes your head spin with shocking beauty and perspective.
