Buenos Aires History

Av.de Mayo is full of surprises and I will mention only one of them.Not too many people know about it or about its story and history,so take your time and go to the Barolo building.They have guided tours which is a must because othewise you are not allowed to reach all the places.One of the curiosities is that the top of the building has a huge light house.When they built it,they build one similar in Montevideo.They were sure that swiching on both lights they could see each other.But it did not happend : the world was round even then !
