Hello, we recently visited Corsica and saw this stunning plant. Can anyone identify the plant please?

Looks like Acanthus, probably Acanthus mollis:

to NGA

But once you have this plant, you have it forever.

Interesting... I've struggled to get one to establish in my garden. I've moved it twice, it's never really flourished, and I've never had a bloom. I don't know for sure when I first got it, it's been several years. Maybe it's new home will be the right answer. I do have problems with slugs eating it and this year gave it a ring of copper pennies. I'd sure like to see it thrive.
