Regina Coeli prison and the Mantova jail in Verona. On 22 June 1963, one day after his friend and successor Pope Paul VI was elected, the latter prayed at his tomb. John XXIII's tomb is located near the tombs of both Pope Pius X and Pope John Paul II. On 3 December 1963, US President Lyndon B. Johnson posthumously awarded him the Presidential Medal of Freedom, the United States' highest civilian award, in recognition of the good relationship between Pope John XXIII and the United States of America. The citation for the medal reads: His Holiness Pope John XXIII, dedicated servant of God. He brought to all citizens of the planet a heightened sense of the dignity of the individual, of the brotherhood of man, and of the common duty to build an environment of peace for all human kind.

His cause for canonization was opened under Pope Paul VI during the final session of the Second Vatican Council on 18 November 1965, along with the cause of Pope Pius XII. On 3 September 2000, John XXIII was declared "Blessed" alongside Pope Pius IX by Pope John Paul II, the penultimate step on the road to sainthood, after a miracle of curing an ill woman was discovered. He was the first pope since Pope Pius X to receive this honour. Following his beatification, his body was moved from its original burial place in the grottoes below the Vatican to the altar of St. Jerome and displayed for the veneration of the faithful. At the time, the body was observed to be extremely well preserveda condition which the Church ascribes to embalming and the lack of air flow in his sealed triple coffin rather than a miracle. When John XXIII's body was moved in 2001, it was once again treated to prevent deterioration. The original vault above the floor was removed and a new one built beneath the ground; it was here that the body of Pope John Paul II was entombed from 9 April 2005 to April 2011, before being moved for his beatification on 1 May 2011. The 50th anniversary of his death was celebrated on 3 June 2013 by Pope Francis, who visited his tomb and prayed there, then addressing the gathered crowd and spoke about the late pope.
