The Grand Prix of San Marino, it was a thing up until 2006. The iconic circuit has been removed from the F1-calendar since that year, but reports have come out that the organization of the circuit want to make a push for a comeback.
According to FormulaPassion, an Italian source, Imola's original plan was to take Monza's place on the calendar. The Italian circuit recently renewed their contract, however, so that's no longer an option. The new plan is to make Imola the Grand Prix of Europe. Baku and Valencia have been previous hosts of the European Grand Prix.
Imola has never been a circuit for much overtaking, not even in the past with the more narrow F1 cars. It wouldn't make for the most overtake-heavy races, which raises the question whether the circuit would add much to the current calendar, where overtaking is already a problem. Italian fans will love it, as they have another opportunity to cheer on their red cars.
The circuit, of course, is most famous for the Grand Prix in 1994, when Ayrton Senna heavily crashed into one of the concrete barriers and eventually passed away.
