Welcome to the world’s largest collection of accordion-family instruments. We showcase 2,500 beautiful, interesting, historical and one-of-a-kind accordions.

Founded in 1993 by Helmi Harrington, Ph.D., we are located in the 100+ year old former Hammond Avenue
Presbyterian Church in downtown Superior, Wisconsin. Our beautiful Hanni Strahl Concert Hall hosts world-class accordionists and other musicians from around the world.

We are home to over a million pieces of accordion music, recordings, books, and other related memorabilia that serve as a wonderful resource for research.

Spend an hour or come for the day, there are so many interesting things to see!
