Hi Gangolf, this is a member of Orchis mascula group inside genus Orchis. Mascula sensu strictu is not distributed in Sardinia, so it should be Orchis ichnusae. I posted comments on other photos showing this species.
"Got tight last night on absinthe and did knife tricks. Great success shooting the knife into the piano. The woodworms are so bad and eat hell out of all furniture that you can always claim the woodworms did it."
