But it wasn’t just any traditional visit by a head of state.
Argentina’s president Cristina Fernandez de Kirchner and Chile’s president Michelle Bachelet were here to celebrate.
In the late 70’s the two South American countries were on the verge of going to war over territorial issues. Then in 1984, they signed a peace treaty under mediation of the Vatican, which the late Pope John Paul II played a key role in.
The visit marks the 25th anniversary of the Peace and Friendship treaty. An anniversary the two heads of state wanted to commemorate along side the countries delegations and other special guests here at the Vatican.
