The Tancredo Neves Pantheon of the Nation and Liberty, built in the form of a dove, was completed by Niemeyer in 1985. It honours the heroes of Brazilian history who fought for freedom and democracy, whose names are inscribed in the Steel Book. On the first floor is a dark room, penetrated only by the light allowed through the stained-glass window by Marianne Peretti. On the wall, black-and-white panels painted by João Câmara depict the Minas Gerais rebellion.
