"Swedish pop music is an important part of our cultural heritage," said former ABBA member Bjorn Ulvaeus, who is one of those behind the museum's creation. "And Abba is one of our most well-known
brands." ABBA shot to fame when they won the 1974 Eurovision Song Contest with the song "Waterloo".
They went on to become one of Sweden's biggest exports with such hit songs as "Dancing Queen" and "Gimme Gimme Gimme (A Man After Midnight)".
The group sold around 370 million records in total and are part of a rich Swedish pop tradition which includes Roxette, Ace of Base, Europe and Kent.
Separate plans for an earlier museum on ABBA were shelved in 2008.
