Barcelona
I really love the work of Gaudi. The buildings are just like painting and everywhere is curve ever the floor of the rool. La Sagrada Familia, the church that is still under construction, the column that supports the church is unique especially after seeing how it formulate by computer.
Casa Batllo is beautiful house with unique interior design and colorful chimneys. Park Guell is where you can find the lizard and La Pedera has a nice museum inside.
Of course, I also visited the Picasso Museum and the fresh market, Mercat de la Boqueria.
