It is the second oldest church in Buenos Aires, a spot you do not have to lose if you come to the city. You can pay a post that gives you access to the clusters and museum of religious objects, historical documents, etc. I tell you a data that we only know the locals. The church is the most popular for the novices of Buenos Aires, the dates for the wedding are taken very much in advance. If you go a weekend, there are still fairs there.
