An absolute MUST visit when you come to Buenos Aires is Palacio Barolo in the heart of the city, not too far from the Obelisco on Ave de Mayo 1370. It is a gorgeous old building, built as a tribute to Dante and his Divine Comedies. The lower floors are put forth as, although not evocative of ;o), of "hell", you then travel up through "Purgatory" to the top most floors - "heaven" and there is a light house at the top that is representative of "God". The tour is about an hour and is well worth the 20$ pesos to walk through this amazing building, built, by the way, by Masons, so there are Masonic symbols in various areas. The architecture and the details in the building are breathtaking and awe inspiring. The elevators alone are worth the trip!
When you reach the end of "purgatory" and enter "heaven" there are tiny little balconies, barely big enough for two slender people, to look out over Buenos Aires in 360 degrees. We were luck and went on a fairly clear day and could see for miles.
I, being me, naturally did not bring a camera with me.... true Sagittarian that I am, and so the web site's pictures will have to suffice to entice you there. Believe it, it is well worth the visit.
