Buenos Aires History
For those that have a penchant for the history of this great city, Google  has recently announced that the latest release of their ‘Google Earth’ maps program has gone ‘4D’, by adding an interesting choice of new dimension – the past, as noted here in Spanish , and here in English . They have done so by adding old maps of certain cities as ‘layers’ over the satellite maps of the earth, so that you can compare past and present.
Luckily enough, Buenos Aires, Argentina  is one of the historical maps included, with a version from 1892 being viewable over the current real-life BA:
Check it out by downloading the latest (free) version of Google Earth  and installing it. To use this cool feature, go to the Layers panel on the bottom left, expand ‘Featured Content’, and then ‘Rumsey Historical Maps’, and select ‘Buenos Aires 1892’, to see how much the city of Buenos Aires has grown since 1892 – look at all that green space! 🙂
