For a small fee of ten euro you can get married in style, at Leuven's 15th century Gothic style Town Hall. The tours of this magnificent structure happen every Sunday at three o'clock.
One thing I did not like about the guided tour is that even though we joined the English tour, the majority of people on that tour were Dutch so the language was mainly Dutch. The guide would explain for 10 minutes or so in Dutch and then summarize it for us in a minute in English. I was a bit disappointed but still happy to have seen the inside of the Town Hall.
Next to this room there is another gorgeous room that you get for free for a day, on your 50th wedding anniversary. I was curious how often that happens and was told that it's every Friday.
