Sculpture of a Phoenix on top of the headquarters of the Mutua Madrileña
The Castellana district is Madrid's financial hub. Starting from Plaza de Colón, you can see traces of the palatial residences that gave the area its distinctive appearance, as well as embassies, government ministries and cultural centres. Its most iconic buildings include the AZCA complex, the Santiago Bernabéu football stadium, the Puerta de Europa towers (Torres Kio) and the Cuatro Torres Business Area.
