Spanish National Statistics Institute
The Spanish National Statistics Institute is located in Paseo de la Castellana, Madrid, near Plaza de Castilla. It was recently renewed by architect César Ruíz-Larrea. The original structure was built in 1973, but what is now only visibile is the fresh new façade, composed of hundreds of coloured panels, which represent the statistics itself. This curious façade is called 'Diafragma Decafónico de Dígitos' and is an artwork by sculptor Pepe Cruz Novillo. It is a transcription system that transforms colours into numbers (0-9). The equivalents for the colours and numbers are: 1 Red, 2 Orange, 3 Green, 4 Rose, 5 Yellow, 6 Dark Green, 7 Violet, 8 Blue, 9 Light Blue and 0 Brown. The 001 panel line for example symbolizes the Spanish area in square kilometres: 504.645. The 002 is Spain's population: 44.108.523, and so on.
