2. La Pedrera This is one of Gaudí’s main residential buildings and one of the most imaginative houses in the history of architecture. This building is more sculpture than a building. The façade is a varied and harmonious mass of undulating stone that, along with its forged iron balconies, explores the irregularities of the natural world. UNESCO recognized this building as World Heritage in 1984.
