Calle Alcalá - spoken Alka-la - is one of Madrid's largest streets. It joins the citycenter with the most famous square Sol ("Sun"), and the suburbs of the town, 15km far apart from Sol. The towerbuilding in the centre of the image houses the Circulo of Bellas Artes (Fine Arts Academy). For an entrance fee of 1 Euro you can both enter in the fantastic turn of the century cafeteria and visit lots of extraordinary fine arts expositions.
