I live in Denmark. So yes. I have seen a map of Scandinavia. People didn't travel. Even here in Denmark which is tiny compared to Norway and Sweden, if you only ever go in a 10-15km radius of your home then there is a good chance you won't see the ocean.
This is true. I concede. However I am not sure that the majority of people were as imobile as you say even in mideveal times there were religious pilgrimages, fairs. Maybe the lowest stratum of non free society lived in a land locked mannor and never saw the sea in Denmark but I wonder if it was the majority of people in a lifetime?
