Chances are very high that you might already have seen those clothes somewhere. On a picture. Or heard something about Benny, Björn, Frida and Agnetha. And could name at least three of their songs. And sing along. Even if you didn't care about this songwriting-contest in 1974. ABBA is definitely the most successful and most known music act from Sweden. In a time where there's a museum for everything, it was high time that there's also one for this supergroup. "ABBA - The museum" on Djurgården opened in may 2013 and since then, people from all over the world come to visit. And I would also say that it's a must-see when in Stockholm. Except if you really cannot stand ABBAs music of course.
Buy the audioguide and you'll learn a lot about the member's carreers before ABBA, the success of the band, and the different rooms you visit. There's even the recording studio or the dressing room on tour. The museum is very interactive, you can record ABBA-songs, perform or dance with the band and download all that at home. The small part of the collection of the golden records (and cassettes and VHS, just in case you remember what this is) is impressive. But to be honest: the real fun thing in this museum are the original outfits. Especially if you didn't grow up in the painted-strangematerial-glitter-colourful-outfit-days, you'll love to take a close look at the original dresses Benny, Björn, Frida and Agnetha wore at the time. You find the dress of the Eurovision song contest (sorry, "Concours eurovision de la chanson" as it was called at the time...) and the famous cat-dresses, among many others. You can buy a lot of merchandise in the shop.
Check the website for all the information. You can buy tickets in advance not to stand in the line but you can also go there spontaneously. Take the tram and leave at Liljevalchs/Gröna Lund/Abba The Museum.
Now do as they tell you: "Walk in and dance out"!
