Another memory of Madrid(Spain) where I lived for 16 years. “El Paseo de la Castellana” is the central big multi-lane avenue in Madrid running north-south/south-north(like Park Avenue in New York City) ending(or beginning) at the 2 major train stations Atocha and Chamartin. “La Castellana” depicts a busy intersection (probably close to “Plaza de Colon”)seen from above in the way I see things.
