Buenos Aires Urban Expansion

A gif depicting Buenos Aires urban expansion in three different time periods: until 1947; from 1947 to 1972 and 1972 onwards (thanks Leonardo Garateguy for the tip).

It's important to stress the avant-garde urbanization of Buenos Aires in contrast to other Latin American cities. Much could be said about this, but it would be out of our purpose with this blog. Besides, Guillhermo Tella probably has much more interesting things to say about it.
