If you want a perfectly preserved mediaeval city, don't look for it here. Go to Brugge. Ghent has not gone through a sort of static time warp like this. The splendid buildings along the Graslei cover a spread of many hundreds of years. The city has had two separate periods of preeminence as a textiles centre, and the Industrial Revolution turned the water colour to "golden." Ugh!
Tourism has probably done it a favour in forcing a general clear-up of the waterways, and their complete restoration will take years yet.
I would not claim to know Ghent properly - or any other of the main cities of Flanders - but having seen at least something of all of them, I rate it as favourite so far.
This may be partly due to the outstanding location of my accommodation - but so what? Everywhere is as you find it, and for me, Ghent was one of the top spots.
Quick Tips:
Take a bit of time here if you can and soak up the atmosphere a bit. This is a "real" city, and there is no great divide between people going about their daily lives and the magnificence of the great buildings. Wander away from the three great towers of Ghent and you are in busy and interesting shopping streets almost before you realise it.
Plan a bit as well. The two museums I write about were not what would have automatically have taken my fancy, had I not done some reading. The city's main museum of ancient art was closed for repair, or I should have been there as well.
I regret missing that and also the Gravensteen [too much up and down for me] and the Beginhof [sheer carelessness on my part.]
I stayed two nights and should have extended my visit if the room had not been taken.
Best Way To Get Around:
The tram is the obvious method between the station and the city centre.
A fairly small area with the three main towers, the Stadhuis, the Graslei and Korenlei and the Gravensteen is easily walked, and should be many times - don't miss seeing it floodlit.
