Any scenic spots around Bologna for a proposal?

Hi everyone,
One of my best friends is planning to propose to his gf during their September holiday during which they‘ll be in and around Bologna.

We found a nice sort of pier in Ravenna, but I was wondering if anyone here had any other recommendations for a scenic proposal spot? Ideally not too public. (Which we fear the pier might be)

Any recommendations welcome! (Yes we also saw theres a romeo balcony proposal spot but that feels a bit weird-awkward)
