Members of the industrial dynasty - founders of Fiat auto manufacturers and often called the "Italian Kennedys" - have lived at "The Castle" in Villar Perosa since the 19th century, while deceased former club chairman Gianni Agnelli was town mayor between 1945 and 1980.
Cristiano Ronaldo scored his first goal for Juventus today, albeit in the pre-season friendly, against a Juventus B team.
But with the extra excitement of being within touching distance of Ronaldo, the supporters couldn't wait and the match was called off 20 minutes before the full 90.
But minutes later a huge swarm of fans invaded the pitch and the game was subsequently abandoned.
The friendly game between Juventus A and Juventus B has been a tradition since 1955 and takes place annually at the Agnelli family estate 25 miles outside of Turin.
Such was the dominance of the Agnellis over the town that deceased former club chairman Gianni Agnelli was mayor between 1945 and 1980.
Ronaldo caused shockwaves this summer by opting to leave Real Madrid to join Juventus in a deal worth £105million.
"It's nice to be here, I'm happy, when I chose to play in Juventus there was not a specific moment", Ronaldo told Juventus TV.
Ronaldo proved good value for the hype, scoring in the 10th minute with a neat finish after breaking a loose offside trap and closing in on goal completely unmarked.
"With the arrival of Ronaldo our expectations are higher for the Champions League".
He played a part in the second goal as well, putting Riccardo Capellini under pressure as a low cross came into the box and the Juve youngster put past his own goalkeeper.
There should be more fans at the match than the entire population of Villar Perosa, with the 5,000 tickets available long-since sold out and even more supporters desperate to try and catch a glimpse of their new idol.
