If you mean something like Greek city states around time of Roman Empire it might be bit difficult. Climate of Northern Europe sets limitations for Northern limitations.
North European Civilization- is it even remotely possible, say, as a contemporary to Greek civilization?
Maybe the Celtoi develop a writing system based on the Greek alphabet.
Did the Celts wipe out/assimilate the dudes who built Stone Henge, or is the distance in time so large as to be irrelevant?
