Glasgow: maybe not as pretty as Edinburgh, but in it’s own way it is. The people are really warm especially to strangers. It’s wetter but not as cold (when the wind comes off the Forth it would cut you in two). Lots of nice museums (The Riverside Museum, The Hunterian Museum, People’s Palace which are all free to enter). Lots of green spaces, it’s known as That Dear Green Place after all. Great music scene now and in the past.
Edinburgh: maybe prettier than Glasgow, but I don’t think so but then I’m biased. The people? Not so warm especially towards strangers. It’s drier but a lot colder when windy. It’s got a castle and now nice new shiny trams. Some nice Art Galleries and museums. They do have the International Festival in August every year which is excellent.
The classical heritage of Rome, the customs of various Germanic tribes and the belief of the Roman Catholic Church were the three roots of medieval culture in Western Europe.
