Casa Mila, which you can use while working in the Square of Kailalonia for a short time, is the second most valuable work of Gaudi after Sadeda Familia. The house to be built between 1906-1912 was designed by the famous architect for Pere Mila, one of the important businessmen of the period. On the front facade of the building, which they call La Pedrera, Gaudi wanted to see what the algae are loaded with a wavy sea. Kaixa de Catalunya Gallery is located.
