A prominent feature of Plaza de Castilla is the Puerta de Europa towers, also known as the KIO Towers. These twin towers stand as emblematic symbols of Madrid's architectural innovation. The towers, inclined at a unique angle, dominate the skyline and contribute to the square's distinctive character.
The square is a hub of activity, surrounded by office buildings, hotels, and commercial establishments. Its location along the Paseo de la Castellana, one of Madrid's major avenues, makes it a focal point for both business and leisure. The Santiago Bernabéu Stadium, home to Real Madrid football club, is also in close proximity, adding to the square's dynamic energy.
Plaza de Castilla is not only a bustling urban space but also a transportation hub. The presence of a major bus station and the Chamartín railway station ensures that the square is a bustling intersection for commuters and tourists exploring the city. The integration of modern architecture, business activity, and transportation links makes Plaza de Castilla a symbol of Madrid's forward-looking urban landscape.
