Apart from a major industrial heritage where at one time over half of all UK shipping and 1 in 4 of all the train locomotives in the world were Glasgow built and a merchant city built upon a massive tobacco and cotton trade.
Crookston Castle from 1400, Haggs Castle from the 1500's, Glasgow Cathedral from the 12th C, the only medieval cathedral to survive the reformation intact, a three storey house, the Provand's Lordship, still sitting there on the High St built in 1471, Glasgow Uni the 4th oldest university in the English speaking world, battles fought within the current city boundaries involving William Wallace and Mary Queen Of Scots, Glasgow Green where Bonnie Prince Charlie and his jacobite army stayed for a week.
The Harry Hopkins Suite in the Millenium Hotel, George Square, the room where Churchill burst into tears when told the USA would join the war effort with the Lend-Lease law, George Square also the scene of Black Friday 1919 when British Army tanks were deployed on the streets of Glasgow to quell a revolution, a city which was also a central location in the 1820 Radical War, the circular office that overlooks Glasgow Central Station where a young John F Kennedy met the US survivors of the SS Athenia sinking, the Glasgow Central Hotel where the first ever long distance TV images were transmitted to by Logie Baird and of course Glasgow's the home to three different football grounds where Hibs won major trophies, Cathkin Park, Celtic Park and Hampden Park.
That's all off the top of my head - every city has plenty of history if you look.
Edinburgh however is a stunning looking city and very atmospheric.
