Say yes in Sønderborg. In Gråsten or Nordborg.
Sønderborg Municipality marries couples from abroad on Fridays, either at the Old Town Hall in Gråsten or at Nørherredhus in Nordborg, not in the town of Sønderborg itself. Gråsten lies on the Flensburg Fjord, a good 25 kilometres from Flensburg. I photograph your ceremony, the congratulations and then your couple shoot, at Gråsten harbour or by Nordborg Sø.
