Pope John Paul II convoked jubilees in 1983 (Holy Year of the Redemption) and in 2000 (the Great Jubilee). In 2000, he greatly liberalized the conditions for gaining the jubilee indulgence. A visit to only one of the four patriarchal basilicas in Rome was necessary (entering through the holy door). To the four basilicas were added the Sanctuary of Divine Love in Rome, and each diocese was permitted to name a location within the diocese where the indulgence could be gained. For instance, the Diocese of Rome added the chapel in the airport at Fiumicino as a possible pilgrimage site. Most dioceses simply named the local cathedral as the pilgrimage site. Multiple visits were not required. On the last full day of the jubilee, pilgrims were permitted to enter the holy door at St. Peter's until late into the night, so no one would be denied the opportunity to gain the indulgence. The requirements of confession, communion, prayer for the pope, and freedom from all attachment to sin remained in place, as for all plenary indulgences.
