If you are not into cemeteries, you can still visit Recoleta and enjoy some of it's other interesting things to visit. Here what I checked out:
Plazoleta Juan XXIII
One of the things that first strikes when you get here is an incredibly huge Ficus. Gomera de Recoleta as its name is, is a few hundred years old. It's assumed to have been planted either 1781 or 1823.
I told you, HUGE!
Moving further we reach the sort of next square with the Basilica Nuestra Senora del Pilar. Interesting fact is that the centerpiece of this gleaming white colonial church, built by Franciscans in 1732, is a Peruvian altar adorned with silver from Argentina's northwest. (Source)

The enormous metal flower blooms anew each day in a pool of water next to the National Museum of Fine Arts, revealing four long stamens inside. Its six 13-meter-long petals open, which takes about 20 minutes, at eight in the morning and slowly close again at sunset, mimicking the actions of a real flower. When the petals are closed, the 18 ton flower is 75 feet tall and 52 feet wide, and when blossomed this amazing man-made flora is an incredible 105 feet wide. (Source)
As nobody really wanted to visit a cemetery, we decided not to go, but based on what I read and saw online it looks quite impressive, plus is the place where Eva Peron is buried.
