Improvements to the monument and sanctuary of Christ the King began in 2006. By 17 May of that year, the Chapel of Our Lady of Peace was inaugurated, under the supervision of architect João de Sousa Araújo. In the following year (17 May 2007), the Pope John XXIII hall was opened, containing eight oil paintings of the same architect, among them images from the encyclical "Pax in Terris" and a statue of the "Angel of Portugal". Similarly, the old high cross from the Sanctuary of Our Lady of Fátima was donated to the Sanctuary of Christ the King, and unveiled on the same day. On 25 November 2005, the newly remodeled main sacristy in the monument's chapel, that featured the original statue of the monument by sculptor Francisco Franco, was reopened.
