This is another historic district, where evidence of Buenos Aires’ past surprises visitors at every turn. In colonial times, Monserrat was the political, economic, social and cultural center of the city. Here the Porteños defended themselves against English invasions. One can still experience history in Monserrat today just by visiting a few of the buildings, streets and underground tunnels that traverse the district. Take a stroll through Manzana de las Luces, contemplate the architecture of the Iglesia de San Ignacio and pass by the Old Cabildo. Then take a rest in the historic Plaza de Mayo. Another option is to sit down for coffee in one of the many cafes. The more restless can learn the two-four rhythm in a tanguería.
