Basílica Nuestra Señora del Pilar: Junin 1892, Plaza Recoleta. It was built by the Jesuit monks in 1732 and it is one of the oldest churches in the city.
In the Plaza of the United Nations there stands one of the more unusual sculptures in Buenos Aires, the "Floralis Generica" by the architect Eduardo Catalano. It´s a gigantic metal flower, with 6 motorised 20 metre high petals that open on special occasions.-
I hope it is not a man eating flower. Run Bob, RUN!!!
