The memorial service will pay tribute to the three-times F1 world champion and the Austrian driver who tragically lost their lives during the 1994 San Marino Grand Prix weekend.
“I think Senna set the standard for all drivers and he was definitely the best of his generation,” Alonso said
“What made him special was his great will to win and the numbers speak for themselves. He always fought right to the bitter end and that earned him the respect of all his colleagues and it's what makes him a legend today.
The Imola circuit will open its doors to the public for the rest of the week to allow fans to pay their respects to Senna and Ratzenberger.
There will also be an appearance of Senna's famous 1988 world championship winning McLaren MP4/4, along with a exhibition of previously unpublished photos and a series of films to celebrate the Brazilian's life.
