Historic Buenos Aires
There is an Obelisk at the Plaza de Republica, which is a public square at the city center where three main streets all intersect. The Palace of Justice is the supreme court of Argentina. The Palace of Flowing Waters is an amazingly beautiful pumping station for fresh water. At the time that it was built, in 1897, Buenos Aires was the only city in Latin America to have clean running water. The Columbus Theater at one time was one of the world's top opera venues.
