Sundahallen is a gymnasium where you can play sports and stuff. Like table tennis, floorball,soccer, shooting, wrestling, bowling, pool and you can swim too. I'm playing in a floorballteam and we practice at Sundahallen. It's a cafeteria there too so you can buy some food and candy. They are going to rebuild sundahallen so it will be bigger and it's going to be an ice rink there too.
