Here in Denmark the bride and groom are walking through a "gate" or "tunnel", when they leave the church. I have no idea what it symbolizes. Usually it's old friends from the army, and that's why most of the time, it's swords that are used to create the gate.
(like here, when the danish prince was married........ again)
Daniel never served, so i think it's some of the young players from his old club, Rosenhųj, who are holding the footballs in the air.
By the way, i love looking into peoples eyes at wedding!
