Rosenborg BK is the most successful club in Norwegian football history, based in Trondheim and competing in the Eliteserien. The club plays its legendary home matches at the Lerkendal Stadion. Founded in 1917, Rosenborg's iconic colors are black and white. The club's name derives from the Rosenborg borough of Trondheim. Rosenborg's history is defined by an era of utter domestic dominance from the 1990s through the 2000s, winning 13 consecutive league titles—a record in Norwegian sports. That period, under legendary coach Nils Arne Eggen, saw the team develop a distinct, possession-based style and make memorable runs in the UEFA Champions League. While their stranglehold on the title has loosened in recent years, Rosenborg remains a perennial contender and a giant of the league, with a squad built to challenge for honors every season. They boast a massive, nationwide fan base and an intimidating home atmosphere. Rosenborg is more than a club; it is an institution that represents the pinnacle of Norwegian football achievement.
