This well planned city was named as Eixample and was one of the district in Barcelona. This city was constructed on the early of the 20th century. The octagonal blocks was divided by a very long, straight road. Even though it looks like a crowded place to live, it has a very good planning which provides an extensive sunlight, improved ventilation and a lot of green space for public use. The image taken from satellites are mind blowing. Two more images after this.
