Central Buenos Aires is intersected by the huge 9 de Julio Avenue, with its famous obelisk. From here it is a short walk to the famous Plaza de Mayo, also known as the Revolution Main Square. This is where we find the enormous Metropolitan Cathedral and the Presidential Palace (the Pink House), with its famous balcony, where both Eva Peron and Madonna have made their appearances. In the middle of the square is the city's oldest monument; the Pirámide de Mayo and the Plaza de Mayo is also the gathering point for the Mothers of Buenos Aires, who continue to protest the disappearance of thousands of young men during the military dictatorship of the seventies. Theirs is a tragic, yet immensely inspiring story.
The centre is also home to the famous Colon Theatre, which is one of the best opera houses in the world and cultural pride of the city. This area is famous for its diverse architecture, glorious buildings built at the turn of the century, many of them boasting a distinctly French style, hence its nickname of the Paris of South America.
