So, what if Brazil in 1960-s because of some reasons, lack of money, political will or something else, decided not to transfer capital city in new city Brasilia? And if Rio remained capital?
Geography-deficient foreigners look less stupid. I can't see much changing otherwise; the millions spent on the city probably go to another portfolio. It may or may not affects whether Tocantins remains a part of Goias or becomes a state.
I know that the whole sense of moving of capital in hinterland was to incent development of Amazonas, but is it possible some other city as a capital, not so far from sea?
Petropolis?
Not Petrópolis. Too small for that.
I'd say either the capital stays in Rio de Janeiro, or it goes to a new city in the same general location as Brasília - the point of moving the capital was to help settle an underdeveloped and underpopulated area; your proposition does nothing for that.
Goiania,capital city of the Goias state alredy existed very near Brasilia(200KM).Brasilia was built because many people earn a lot of money in it´s construction.
In Rio what buildings were the royal palace, presidential palace, and national legislative building? What became of them after the government moved?
