Casa Batlló in Barcelona, Spain is one of the most unique buildings I have ever seen. One of Antoni Gaudí’s most famous works, Casa Batlló is also called The House of Bones. The House of Bones was given this name because of the skeleton structure that is throughout the inside and outside of the building. The outside is also covered in beautiful colors that, I think, makes it look like a dragon. This is truly one of the most special buildings I have ever seen and was amazed at how smooth the interior and exterior were where they curved. It all flows so nicely and looks smooth and cohesive in every area. I also like that the curves are not only vertical but they have depth to them and the windows curve with the rest of the building.
