It was conceived during the national shock following the death in 1985 of president-elect Tancredo Neves, the first elected civilian president after twenty years of military rule.

This is housed on the third floor between the Painel da inconfidência, a sculpture in honour of the martyrs of eighteenth-century uprising in Minas Gerais and the stained glass by Marianne Peretti.

The Pantheon of Motherland and Freedom, Tancredo Neves in the Praça dos Tres Poderes in Brasilia was designed by architect Oscar Niemeyer in 1985.

Its foundation stone was laid by French President François Mitterrand on 15 October 1985 and the Pantheon was inaugurated on 7 September 1986.

On the outside, on top of a tower built on the diagonal, burns an eternal flame which represents the freedom of the people and the country's independence.
