Our civil wedding ceremony
First we had our civil marriage ceremony in the gothic townhall of Leuven. You have to wait in a side gallery of the building while the previous ceremony is going on at the other side of the window. They were running late on schedule so the previous couple only got in when we arrived. At the moment the wedding was pronounced and we heard the applause we were tempted for a second to knock on the window and wave extensively and give them thumbs up or something....but we behaved and didn't disturb their moment :p.
The ceremony was as expected not much special: reading out loud of the law texts concerning marriage, a few questions to be answered with yes and a little speech to congratulate us.
As to answer your questions: we didn't get married by the well-known mayor Tobback. He married the couple before and after us. I guess he was alternating with is CD&V alderman colleague ...it was the day before the elections :). He was standing outside the hall though and congratulated us when we walked out.
After the ceremony you get to walk out at the big staircase in front of the townhall leading to the big market square showing off to all the tourists :p
