I'm thinking it's perhaps cow parsnip (Heracleum sphodylium). I can't be certain as I don't know how commonly it's found in your area although I do know it occurs there. When the plant is still young, leaves may not be as divided or show the 'maple leaf' shape as strongly.
If you think this might be correct, please be aware that cow parsnip and giant hogweed are very similar looking. But with giant hogweed, you need to exercise caution getting rid of it as contact with bare skin and the plant can result in skin rashes and blistering due to photosensitivity.
Yes its hogweed, Heracleum sphondylium grows to about 2.5 meters tall, generally considered a perennial, large umbels of white flowers on top and contains blistering agent in its sap, flowers from April to November, Distribution throughout Europe.
Its cousin Giant Hogweed, Heracleum mantegazzianum is twice are large and only really grows next to water this one however has a photo-sensitive blistering agent- very nasty that continues to be painful for many months afterwards. both when dug up have large tap roots going down quite a way 30cm+
