It took Loftus Versfeld less than a day to become sold out, when tickets went on sale for this afternoon's first Test between Ireland and South Africa.
More than 50,000 tickets were snapped up almost instantly back in March for the unofficial World Cup homecoming.
There's a sign outside the ground in Pretoria that reads 'Welcome to the Capital of Rugby', and it's not far off.
"I'd go as far as saying it's a religion for these people over here, the lift their team has given them over the last two World Cups and going back further a long time before that" Ireland captain Peter O'Mahony said about their hosts.
The 34-year-old wasn't being hyperbolic with such a claim. The arrival of the four South African franchises to the URC in 2021 has since given those of us working the rugby beat a real sense of how passionate the Springbok fans are. Whether it's articles, podcasts or videos, they devour the lot.
The Irish players have also grown used to playing in the big South African stadiums.
Munster and Leinster both played at Loftus in recent months, with Munster winning that game, while they've also won away at the Lions and Stormers.
Their most recent win against the Stormers came in Cape Town in the 2023 United Rugby Championship final, where a raucous 50,000 crowd saw them upset the defending champions.
But O'Mahony believes even a URC final won't be much preparation for a Test match atmosphere in South Africa.
"It was a great atmosphere and experience [in the 2023 URC final], it was a good game, but I'd still argue it's going to be a different animal tomorrow.
"There'll be pockets of Irish, but it'll be a South African crowd tomorrow.
"I'd look back to the 1995 World Cup, some of the lads on my team won't be old enough to remember it.
"I can remember it being a special time in rugby, so I'm probably out of place saying I know how much it means to them. I probably don't, but I know it means a hell of a lot.
"I'd imagine their support will be huge for them tomorrow and we need to understand that," he added.
If rugby is a religion, then O'Mahony's opposite number Siya Kolisi (above) is their saviour.
The 33-year-old resumed the Springbok captaincy after a frustrating season for his club Racing 92, and O'Mahony says he has nothing but admiration for his fellow blindside flanker.
"Two-time World Cup winning captain, it doesn't get much bigger than that, does it?
"You can see from the outside the influence he has on his group, not only that but the influence he has on people in his country, the inspiration he gives to them.
"He's an incredible athlete when it comes to tomorrow, but the overall picture of the person that he is, I don't know him personally, but he seems to be a huge character and a huge character for his nation.
"He's leaving an incredible legacy," O'Mahony, who will win his 106th Irish cap today, said.
The main talking point leading up to this game has been Jamie Osborne's upcoming debut at full-back, with O'Mahony yesterday backing the uncapped Leinster man to hit the ground running.
It will also be a significant day for O'Mahony's Munster team-mate Craig Casey (below), who starts at scrum-half for the biggest game of his international career to date.
"I've been lucky enough to track Craig's progress since he was a young fella, coming into Munster's setup. I think from day one he's been an incredible source of energy, source of enthusiasm, professionalism, hunger, all those things you see from him on the pitch.
"Seeing his development with the way he's gone, really taking a hold of games with his half-back partners and controlling games well, learning to be calm while big games are unfolding.
"I think the progress he's made over the last six or 12 months has been huge as well. The experience he's taken from being in camp and having some Test games, and playing a lot for Munster has accumulated for him really tidying up his game and becoming a very complete footballer, a complete scrum-half."
As expected, the veteran flanker had little to say about some of the sideswipes taken in the media by some of the South Africa players in recent months, insisting they will do their talking on the pitch tomorrow.
However, he was bullish about the suggestion that the Irish squad would be physically and emotionally drained in their final games of a season that's now into a 13th month.
"People, I'd imagine, are talking about it being a long season but I've never seen a fresher group of people.
"Unfortunately, we were all out at semi-final level in the URC, but it gave us a nice week to get organised and hit the ground running. We got into camp a little bit earlier than would.
"I think it would be wrong or strange if you didn't stand up a little bit taller when you walk into this Ireland camp.
"It's a great environment, a great place to be and it's funny any of the niggles, the sore bits fade away in this environment because of what it means to you, because of the group and who you're being coached by.
"You would see guys after the few days, guys have been beaten but they've dusted themselves off and we've an unbelievable pep in our step going training, enjoying each others' company and, as I said, it's an unbelievably energised group.
"It's going to take probably our very best performance of this group's lifespan to win over here, but we've ticked off a lot of big occasions and that's why you play the game for Test matches and opportunities like this," he said.
