The tomb of Pope Benedict XVI under St Peter’s Basilica can now be visited by the public.

The pontiff was buried on January 5, immediately following a funeral in St Peter’s Square, and his tomb lies in the grottos under the basilica’s main floor.

The Vatican announced on Saturday that the public could visit the tomb from Sunday morning.

Benedict had lived since 2013 as pope emeritus, following his retirement from the papacy, the first pontiff to do so in 600 years.

He died on December 31 at the age of 95, in the Vatican monastery where he spent his last years.

On Thursday, his long-time secretary Archbishop Georg Gaenswein imparted a final blessing after Benedict’s body, contained inside three coffins – the cypress one displayed in the square during the funeral presided over by Pope Francis, a zinc one, and an outer one hewn from oak – were lowered into a space in the floor.

The remains were placed in the former tomb of Benedict’s predecessor, St John Paul II. John Paul’s remains were moved up to a chapel on the main floor of the basilica following his 2011 beatification.

Some 50,000 people attended Benedict’s funeral, following three days of his body lying in state in the basilica, an event which drew nearly 200,000 viewers.

The name of Benedict, the Catholic church’s 265th pontiff, was engraved on a white marble slab, the Vatican said.

The Vatican did not say whether Pope Francis had privately visited the completed tomb of Benedict before public viewing was permitted, or might do so at some other time.

On Sunday morning, Francis led a ceremony for the baptism of 13 babies in the Sistine Chapel.

Later, greeting pilgrims and tourists gathered in St Peter’s Square for his noon blessing, Francis quoted from a 2008 homily by Benedict, in which the late pontiff spoke about salvation.

Drawing inspiration from his predecessor’s words, Francis said that the faithful when judging others, including in the Catholic church, should apply not harshness but mercy, “sharing the wounds and the fragilities” and avoiding divisions.

Francis has been criticised in some quarters by those who favoured Benedict’s more conservative stances because his funeral homily made only a mere mention of the late pontiff.

While Benedict and Francis had openly spoken of each other with respect, tensions festered for years between loyalists of both men.
