*Teatro Colón is ranked the third best opera house in the world by National Geographic, and is acoustically considered to be among the world's five best concert venues. It is bounded by the wide 9 de Julio Avenue (technically Cerrito Street), Arturo Toscanini Street, Tucumán Street, as well as Libertad Street at its main entrance. It is in the heart of the city on a site once occupied by Ferrocarril Oeste's ''Plaza Parque'' station.
