Avenida Rivadavia 5
Now you think probably did a Lourdes picture come in between? Well this is also something on Avenida Rivadavia. There is a Colegio de Lourdes on it (obviously a Catholic school). Next to it is a paroquia dedicated to the Virgin Mary. This is a kind of a shrine outside dedicated to her. You always find people there for a prayer. I was lucky there was no one there at that specific moment.
What is also nice to mention. If you are in the bus and you pass for example this spot you will see people making a cross. Also folks walking buy or in cars.
