Man Urinates on Altar at Vatican City's St. Peter's Basilica

Tourists were left stunned as a man brazenly urinated on a Vatican altar during Holy Mass – in full view of hundreds of worshippers.

The shocking act of desecration unfolded inside St Peter‘s Basilica on Friday morning.

The unidentified man climbed the steps of the Altar of Confession – one of the most sacred spots in Catholicism, where the pope himself traditionally celebrates mass.

Once at the top, he dropped his trousers to his ankles and began urinating over the holy site, according to Corriere della Sera.

The disgusting scene took place during the 9am Holy Mass where stunned visitors looked on in disbelief.

Security officers raced towards the man as the crowd gasped.

Cops grabbed him and dragged him away from the altar as he finished his vile act.

But before they could escort him out, the man bent down so he could pull up his jeans – flashing his bare backside to the horrified onlookers.

The clip, filmed by shocked tourists, has since gone viral online.

“That is absolutely shocking and deeply disrespectful,” wrote one viewer.

“This is vile,” said another.

“There is definitely not enough security here,” a third person added.

It remains unclear whether Pope Leo XIV was present at the time.

The Vatican has not yet released an official statement.

But according to reports, the Pope was “shocked” when he heard what had happened.

The Altar of Confession sits directly beneath Michelangelo’s dome and is considered one of the holiest places in the catholic world.

It’s where the pope often celebrates major masses – and where, in April, Pope Francis was laid in response for public viewing before his funeral.

Because of its significance, the Altar has repeatedly been targeted by intruders in recent years.

In February, a man climbed onto the same altar and knocked six candelabras to the floor.

In June 2023, a naked Polish man leapt onto the altar during Mass.

He didn’t speak or cause further damage, but he had the words “Save children of Ukraine” scrawled across his back.

Following that stunt, the Vatican held a penitential rite to cleanse the grounds – a ceremony required under canon law to restore sanctity after desecration.

Friday’s incident has sparked renewed questions about security inside one of the world’s most sacred and most visited churches.

St Peter’s Basilica attracts millions of visitors each year, with tourists often crowding the altar area to witness the grandeur of Vatican ceremonies.

Authorities have not said whether the man has been arrested or charged.

The Vatican’s Holy See Press Office is yet to comment publicly.

The shocking desecration comes amid a wider crackdown on tourists and foreign visitors in Italy.

Earlier this year, the Italian government tightened citizenship laws, making it far harder for Australians and other foreigners to get passports by descent.

In Venice, officials doubled the entry fee for day-trippers and expanded the days it applies.

Last year, two unruly tourists caused outrage after stripping off and swimming in front of a cemetery.

They were spotted by commuters leaving their clothes on the banks of the San Michele Cemetery before plunging into the water.

The Isola di San Michele is home to both a cemetery and a church, and is the burial site of several famous figures, including Russian-born composer Igor Stravinsky.

The repeated stunts and security breaches at major religious sites have raised concerns about how well such locations are being protected.

Friday’s stunt – carried out at the heart of the Vatican – is likely to intensify calls for a security overhaul.
