It is not the most beautiful square in the city but, with this size, it unites the old and the modern sections of the city. Plaza de Catalunya is a symbol of the city, one of the most famous and the place where half of the city meets up.
It is a very easy place to get to, many subway and suburban train arrive there, as well as bus and nitbus (night bus) lines. To go to the airport the Aerobús starts from Plaza Catalunya and there is also a Tibibus going to the Tibidabo attraction park.
On Plaza Catalunya there are official monuments, bank headquarters, shops (a huge Corte Inglés, FNAC), etc.
