Alonso is a two-time victor at Monza, initially in 2007 during his ill-fated season with McLaren, and again last year with Ferrari, a highlight of his career.
The two triumphs could not be in greater contrast as he said: "They were very different.
"In 2007 it was like winning a normal race at another circuit. The reaction from the tifosi (Ferrari fans) was not the same.
"Last year there were much more emotions, and not just the race, but the whole weekend.
"When you drive for Ferrari there is the support from the fans, and a lot of activities throughout the week for our team.
"Then when you win and you see the start-finish line full of the tifosi on the race track who are so happy that a red car won the race, an Italian car won the Italian Grand Prix once more, it's a very special feeling."
It is those feelings and such scenes that will be driving on the double world champion this weekend, even if the title picture is becoming forlorn.
Although Alonso trails championship leader Sebastian Vettel by 102 points, he appreciates just how much this weekend means to everyone connected with Ferrari.
"There is a special atmosphere, a special motivation this weekend for all of us," added Alonso.
"You have the mechanics and engineers who have their families in the grandstands and they have people they know in the paddock.
"Of course, we all give 100% every weekend, but in Monza there is this extra care in everything we do.
"We want everything perfect, from practice through to Sunday, so I am sure all of us will make an extra effort to do everything perfect this weekend."
