Brugge at night...
It's very quiet at night. The streets are more or less deserted, and it doesn't really seem like too many people actually live in the city center. It didn't feel unsafe at all- the worst we saw the whole trip was dog poo on the sidewalk, and other than that it was a squeaky clean place.
Amusingly, at 4am I got woken up by a loud, drunk American who was outside my window asking the world where is hotel was. It's easy to get lost in Brugges. If you like beer, it's also really easy to get drunk.
Bruges was important port city for ages. Here, there was a huge cloth and textiles industry. They still make really gorgeous lace and needlework in the traditional way.
Some of the interiors were incredible. While the churches aren't as flashy and huge as those in France, they made up for it in the detail and liberal application of color.
There was also fantastic food to be had. Aside from wonderful mussels and perfectly cooked frites, they had some very good restaurants to choose from. Lots of very fresh seafood and french-inspired cooking.
