The team is touring Paris, London and Rome, and many in the group expected it to be the rugby trip of a lifetime.
But little did they expect to be in Rome when Pope Francis died earlier this week.
College director of rugby Nathan Hull said it was a "very unique" time to be in Rome.
"Despite the solemn atmosphere of Rome at the moment, it has only enriched the cultural experience of the tour.
"The students are aware of the significance of the Pope passing, but they may not yet fully grasp the impact of being in Rome when it has happened."
Mr Hull said there was a heightened media, police and military presence in the city, and all the flags were at half-mast.
"It is clear to see the number of people who are impacted by his passing.
"Rome is still very busy, particularly around Vatican City, with locals and travellers queuing for hours to pay their respects," Mr Hull said.
The 25-strong tour group arrived in Rome on the same day Pope Francis died, so they expected several of their pre-organised tours to be cancelled, he said.
"However, we were still able to tour Vatican City and enter the Sistine Chapel.
"The other notable tourist attractions are all still open."
Pope Francis’ funeral will be held today, outdoors in front of St Peter’s Basilica.
