The place is a homage to Dom Bosco, an italian priest who had a view in a dream of a city "between parallels 15 and 20, in the south hemisphere, a rich place, with a lake close by". He died more than 50 years before Brasília was even mentioned. And you can guess where Brasília is, right? For this reason, Dom Bosco is the patron saint of Brasília.
