A museum dedicated to Swedish supergroup ABBA will open in Stockholm next spring at the Swedish Music Hall of Fame. With almost 400 million records sold, a musical that shifted 50 million tickets, and the highest-grossing musical movie of all time (Mama Mia, starring Pierce Brosnan and Meryl Streep), the group have remained a permanent pop culture fixture despite disbanding 30 years ago.

Organizers hope the permanent exhibition—the museum is being designed by Celsing Arkitekter on the capital’s historic Djurgården Island—will bring in half a million visitors every year to sing along with life-sized holograms of Anni-Frid Lyngstad, Agnetha Faltskog, Björn Ulvaeus, and Benny Andersson. The museum will also feature music, lyric sheets, and stage costumes donated by the band.
