Not just for techies, the National Science and Technology Museum will engage everybody. You'll see the first computer used in Spain (a monstrous IBM 650 from 1959), and the entire front section of a Boeing 747. Perhaps most fascinating is the room displaying innovations from every year of the 20th century – a 1965 SEAT 600 (the tiny car that 'got Spain motoring'), a Sony PlayStation (1994), a 1946 state-of-the-art pencil sharpener and much more.
