Buenos Aires is also different from the other cities in that it does not have a central 100 x 100 metres plaza. Plazas thereare, but either they are not central, or they have other sizes. Along the roads towards the railway and bus stations of Retiro there are three plazas – that are more like parks than plazas – just next to each other. This picture is taken from Plaza Libertador General San Martín towards Plaza Fuerza Aérea Argentina. (San Martín is the biggest of all the Argentine national heroes.)
